Alachua County SKYWARN

AFN Web Pages Back In Operation...

2011-10-03T11:59:00.008-04:00

  The problems with AFN have now have been fixed. Summarizing...

  Early yesterday morning, around 3am, FTP access to AFN had failed. The AC-EMWIN server was logging repetitive errors in communicating with the AFN server. During this time, no weather bulletins or graphics were able to be uploaded to the AC-SKYWARN web site. However, the AFN web pages were at least *accessible*, if but for some broken image links, such as the watch/warning map, the accompanying legend, and the current readings graphic for the Gainesville Regional Airport. The problem remained for the whole day due to the fact that it was a Sunday and there was no one at CNS to take care of the problem. AFN web access and email finally died altogether sometime around 7pm, last night, and remained that way until about 9am, this morning, when AFN admin was finally able to get right on it.
  Meanwhile, AC-EMWIN services to email, cellphone, pager, FAX, listgroups, Facebook, and Twitter were NOT affected by the AFN outage, and continued uninterrupted.

  An email from AFN admin this morning confirmed that a file system had filled up and had to be manually emptied.

  The following web pages are again operational:

We'd like to thank everyone for their patience in dealing with this.

Kudos to the AFN team for getting on it pronto, this morning. Thanks guys! You rock!

AFN FTP Down...

2011-10-02T11:32:00.000-04:00

It appears AFN (Alachua FreeNet) FTP is down. The web pages seem to pull up okay, but nothing new is being sent to AFN. This means that anything
that is FTP'd to the site (bulletins, graphics) are not being updated, right now.

I've confirmed this with the AC-EMWIN server and it is definitely experiencing errors whenever it tries to connect to AFN. It began about 3am, last night. Of course, this is occuring on a SUNDAY. :( I *have* sent emails to AFN admin about it, though.

Note that this ONLY affects things under AFN, not with the entire AC-EMWIN system. That is, bulletins sent to email, pagers, cellphones, listgroup mail, Facebook, Twitter...these are all okay and unaffected.

AC-EMWIN "Adjustments"

2011-08-26T13:02:00.004-04:00

Downloaded an additional map database for the AC-EMWIN server software which allows painting of the TS/hurricane watches/warnings along the coastline. Had to take the server down very quickly - no one really noticed - in order to implement it.

Also made a few tweaks to the software not really worth mentioning they're so insubstantial.

Added a link to the NHC to the AC-SKYWARN page's side navbar, as well.

Major (Background) Update To AC-SKYWARN Web Page

2011-08-09T11:49:00.003-04:00

I decided to go ahead and finally upgrade the AC-SKYWARN web site with changes that I've been meaning to make to them for quite some time, now.

It used to be such a pain whenever I'd want to make the slightest little change to the ACS web pages. If I wanted to change a word, a sentence, add or remove a graphic or something...it always involved making that change multiple times. Why? ...Because of how many different "templates" that I had for just the main front page, alone. Whenever the Hazardous Weather Outlook is issued by NWS-JAX, the AC-EMWIN system reads the "Spotter Activation Statement" section and picks from an assortment of different front page templates each with different spotter activation notices used in the scrolling marquee at the top. There are something liek 8 or 9 templates, altogether. The statement could say "SPOTTER ACTIVATION IS NOT ANTICIPATED AT THIS TIME"; or it could say "SPOTTER ACTIVATION MAY BE NECESSARY LATER TODAY", or "SPOTTERS ARE REQUESTED TO ACTIVATE ATT". So if I wanted to change anything in the static text in each front page template - such as changing a news headline - I'd have to do it in all 9 templates. Same if I wanted to change a sidebar menu navigation button. You can see how frustrating that could become.

So I made use of something called "IFRAME" in HTML code, which allows me to call upon a SEPARATE EXTERNAL FILE and import that into the page. I'm doing this with the date across the top left. I import another external file for the main body text. I import yet another for the sidebar navigation menu. This way, whenever I need to change something in the calendar date script, the change occurs across every page which makes use of it. If I need to make a change to the manu sidebar, that change happens across ALL of the subpages that use it. If I make a change to the main body of the front page...ALL of the various templates will pull that one same file. I no longer have to duplicate my work. That will save me so much time and effort.

Spotter Training Class Notice:Alachua County - December 9, 2010

2010-10-23T12:29:00.002-04:00

Two years and eight months since OUR last spotter training class, and eight FLAGLER County spotter classes later, a spotter training class has FINALLY appeared on the NWS-JAX board for Alachua County...

Alachua December 9, 2010

A PERSONAL COMPLAINT: Spotters are required to have refresher training every two years. Because of the immature actions of quite a number of Alachua County ham radio operators who have caused a number of pretty serious problems, our own local area spotter program has pretty much disappeared and been dissolved down to a web page only, while Alachua County has been *severely* prejudiced and NWS employees have actually been *afraid* to come down here to give any classes at all for 2-3/4 years. Angie does classes for every *other* county in the NWS-JAX CWA but seems utterly *frightened* to show her face here, anymore. So many bad things have happened. Government officials took actions based on gossip, and now they're responsible for those actions. They made some serious mistakes of judgment and management and they don't know how to APOLOGIZE much less FIX the things that they were duped into doing by the hams. ANY acknowledgement opens them up to a lawsuit. At the same time, FLAGLER County has had it's *pick and choose* of up to THREE CLASSES A YEAR - at least EIGHT since we had OUR last class. ...Maybe more - I'm still researching it. That's an inexplicable favoritism, and it's just not right.

Regardless of what those hams have done, taking it out on innocent people who had NOTHING to do with it all is NOT right. The spotter program, and the training classes, MUST continue, regardless. If NWS is worried for their safety, then they can always get security to accompany the instructors. But spotters *must* be refreshed every two years, regardless. That is an NWS mandate.

Meanwhile, I propose that if the hams are a problem, THEN STOP COOPERATING WITH THE HAMS UNTIL SUCH TIME AS THEY LEARN. The rest of the ham community will be forced to follow through and get ON them. It WORKS. You just need *solidarity* to make it happen. There is a serious problem with the local ham community and it needs to be addressed head on. If need be, I would suggest putting a two-year cessation on all cooperation with ALL Alachua County ham programs, and *force* them to sit down and talk amongst themselves about self-policing and doing the right thing and taking charge when bad apples cause harm to others. Without that, ***there are no consequences*** and nobody has any reason to *stop* what they're doing. PUT YOUR FOOT DOWN...and it shocks people, makes them think. GARS, GARC...these clubs need to be made aware of what their members are doing, and to seriously stop and think about such things, and stop *avoiding* the very serious things that are right in front of their faces. These guys don't like to acknowledge the bad. They're like some abuse victims...they continually turn a blind eye and let the abuse continue to happen, thinking if they just ignore it "it'll go away on it's own". You have to take charge, or you'll just keep getting hit. At this point, their members have caused so much harm that they could face lawsuit and total dissolution.

Myself, so much harm has been brought to me personally, and to other people, and so many crimes have been committed, that I'm *actually* thinking of bringing a real lawsuit against some people in NWS-JAX *and* against Alachua County government. This is SO BAD what has been done! (sigh)

Meanwhile, reinstate the non-ham *civilian* spotter core - which worked perfectly and HAD no problems because it stayed SEPARATE from the ham community (while still allowing COOPERATION between hams and EM). This is WHY Alachua County SKYWARN was civilian-run and avoided hams and EM...we didn't want the damned politics and egos. WE didn't NEED dues, donations, or grants. We did our job and JUST the job that we were supposed to do: LOOK UP, and REPORT! That's IT! There is NO OTHER DUTY for a spotter! Security background checks, incident command training, EMRISS training, CERT membership, ham membership, emergency management security clearance, classes held inside buildings REQUIRING any of the above...these things are not supposed to be required for a spotter. That's ARES, RACES, etc. Those are totally separate things. SKYWARN can work WITH those groups. But it is supposed to be separate and of it's own. When you try to join it with these other things, problems happen, and there is politics, and unnecessary over-management for something that is supposed to be very simply run.

If THIS class gets postponed, then I *strongly* encourage people to make complaints to NWS-HQ in DC and call attention to it all. This is ridiculous. It really needs to be brought to public attention if these guys can't start getting on the ball and taking charge.

Webpage Watch/Warning Map Temporarily Broken...

2010-09-09T12:25:00.002-04:00

Bare with us. We just upgraded to a new beta version of the EMWIN software and apparently there is a bug which prevents the map from being properly transferred to the web site.

We're working on this as we speak.

Gust Front Funnel Cloud ('Gustnado')June 29, 2010Gainesville, FL

2010-06-30T17:35:00.008-04:00

Date/Time: June 29, 2010, 5:44pm ET
Location: Gainesville, Alachua County, FL

Photo by Dr. Steven A Robicsek, MD, PhD. Taken June 29, 2010 at 5:44pm, from atop the Seagle Building on W. University Avenue, looking west at the Ben Hill Griffith Stadium.

This is not actually a "tornado", but something more like a large dust devil. If you remember your spotter training, a true funnel cloud "hangs pendant from a wall cloud." Gustnadoes are actually not part of or connected to the cloud base. From the New World Encyclopedia...

"A gustnado (gust front tornado) is a small, vertical swirl associated with a gust front or downburst. Because they are technically not associated with the cloud base, there is some debate as to whether or not gustnadoes are actually tornadoes. They are formed when fast moving cold, dry outflow air from a thunderstorm is blown through a mass of stationary, warm, moist air near the outflow boundary, resulting in a "rolling" effect (often exemplified through a roll cloud). If low level wind shear is strong enough, the rotation can be turned horizontally (or diagonally) and make contact with the ground. The result is a gustnado. They usually cause small areas of heavier rotational wind damage among areas of straight-line wind damage. It is also worth noting that since they are absent of any Coriolis influence from a mesocyclone, they seem to be alternately cyclonic and anticyclonic without preference."

This is truly an amazing shot. It's difficult enough to catch any KIND of a funnel here in Alachua County; but to catch one placed perfectly right next to the stadium like this is sure to destine this particular photo for some small amount of fame in the least. Congratulations to Steve on nailing this one! This is a great shot!

I've talked to Bill Quinlan, TV-20 Meteorologist, and he advises that in talking with the NWS they thought they were seeing a convergence of two outflow boundaries in the vicinity. Bill said that he was looking at the radar when this was actually happening and he said that this funnel occured at the very outside edge of the storm, where the outflow/gust front was.

We're not exactly sure just WHERE the funnel is actually touching down...behind the O'Connell Center?...over Lake Alice? It is obviously picking up a lot of dust. We know that the point of photography is at the Seagle Building. And the funnel is located between the southern edge of the west wall of the stadium and the south end zone score board (the building with the antennas on top of it). This narrows things down a bit. But now we need someone at ground level from that area who actually saw it so that they can point to us a differrent specific direction and this will allow us to accurately pinpoint exactly where the event actually occured. So if there's anyone who lives in any of the dorms in that vicinity who actually saw this, please do contact us so that we can try to narrow this down more.

This photograph demonstrates perfectly how there are things out there which can LOOK like a funnel cloud or a tornado, but which actually are not. This is an excellent "look-a-like", and I've been hunting for these kinds of photographs for a while.

(This may well be the first-ever photograph of a gust front funnel ever taken in Alachua County.)

EMWIN Downlink Frequencies Under Attack By Broadband Interests

2010-06-09T11:37:00.003-04:00

IMPORTANT NEWS FOR EMWIN USERS:

For those SKYWARN spotter and ARES/RACES groups across the US which make use of EMWIN to distribute weather bulletins to their spotters, hams, and to their local communities, some kinda scary news...

THE PROBLEM:

From the EMWIN-Users listgroup: "Of special interest to EMWIN users and vendors is FCC Public Notice DA-1035 (ET Docket No. 10-123) released on June 4, 2010 calling for public comment on the extent and manner of use of the 1675-1710 MHz frequency band by non-federal users."

The FCC is calling for comments on the feasibility of the idea to share (or I'm not sure...possible take) the current frequencies now used for EMWIN downlink with broadband (cellular) services, which could interfere with (or cease) EMWIN downlink for many users across the country and other parts of the world...including the downlinks thousands of Emergency Management Agencies now enjoy across the nation and even abroad. Problem is, they've only given us until the 28th to respond. ...Of THIS month. That's right. As of today (the 11th), you have 17 days to find every possible example of EMWIN use across this country and abroad - and to have each and every one of them respond and make us look legitimitely important. Do you know how to get thousands of Emergency Management and Civil Defense Agencies - who apparently don't even at this time know that this is even happening much less that they are supposed to defend themselves - to suddenly up and grab muskets and defend the use of their EMWIN systems with comments?

EMAs and CD agencies use EMWIN to get weather and emergency information SIMULTANEOUSLY with their NWS kin. The EMWIN data downloaded directly from the GOES satellites is received and redistributed IMMEDIATELY - on the order of a whole two MINUTES faster than the NWR weather radio system does. In severe weather and emergency situations, two minutes is a LOT and allows Emergency Managers and CD agents that much more time to decide what to do. That can save lives.

In the Pacific, and even recently in Haiti where our government just GIFTED an EMWIN ground station, EMWIN is the only source of hurricane and other emergency-related information. They have nothing else.

There are many places around the country that don't HAVE cable or DSL. In these places, EMWIN is much appreciated.

Sharing with broadband could introduce interference problems which could mean loss of transmitted data and the thought that the FCC might even consider this acceptable is kind of ludicrous. What are they thinking?

There's the thought that EMWIN could be distributed by other means, such as over the Internet. I disagree with this, however. The whole reason EMWIn was originally created was to give Emergency Management Agencies and Civil Defense agencies a means with which to receive the latest weather data as early as possible to give the fastest possible reaction time. Forcing redistribution through the internet is just non-feasible. It introduces likelihoods for serious delays. The more servers you have between the satellite and the end user the more liklihood for breakdowns, downtimes, susceptibility to things like hackings and DOS attacks, or delays from just plain traffic overload. Weather data distributed via the internet could introduce unacceptable delays from hours to days, which would make EMWIN data non-feasible any longer as an Emergency Management tool, a Civil Defense tool, or anything more than a notification method of "convenience" and "curiosity" than anything that could be used to help save lives by giving the fastest possible notification times. Internet distributuion would introduce some of the SLOWEST POSSIBLE notification times.

EMWIN has been around for many many years, and it is not the same itty-bitty thing that it started out as. It has improved greatly, adding more bulletins, more useful graphics, and we were right in the middle of a transition to even FASTER downlink speeds when the FCC came along with THIS stupidity.

EMWIN doesn't just offer weather bulletins. It offers civil emergency-related bulletins such as warnings for hazards such as earthquakes, tsunamis, avalanches, road hazards, hazardous materials accidents, telephone outages, law enforcement emergencies, nuclear hazards, attack warnings, etc. It offers varioius graphics, too, such as satellite and radar and forecast plots.

The EMWIN system costs little to set up and maintain. The software is cheap and can do many awesome things - including starting other programs on issuance of a watch or warning, or setting off external equipment such as flashers or sirens using X10 capability.

Scary is that some towns across the US actually depend on te EMWIN downlink to set off their sirens during weather emergencies.

Here is an email from the EMWIN Staff, sent to the EMWIN-Users listgroup.

Here is a link to the actual FCC Notice. Use this document's guidelines to also respond with your comments.

INTERESTING OBSERVATIONS:

- Sudden odd behavior on the part of NWS employees. Emails to NWS (especially EMWIN-related-) employees with questions having anything to do with the EMWIN issue go unanswered. This is highly unusual considering that the employees emailed NEVER ignore an email and are ALWAYS otherwise VERY helpful and anxious to respond. This would seem to indicate that there is some sort of a gag order is in place. Should we contemplate requesting FOIA copies of any internal memoes so ordering employees to keep quiet?

WHAT CAN WE DO?

We need to write the FCC and get as many people and orgainzations and agencies to respond as possible. Harp on our numbers - how many of us are actually using the downlink; and on the SPEED with which EMWIN allows us to receive the bulletins - on par with our NWS counterparts, often on the order of minutes before they actually go out over the NWR or are received using internet-based commercial resources. Mention how EMWIN is used in your area. Be specific.

Don't let apathy in. Don't GUESS at how this battle will go and assume that there's gonna be a last-minute cavalry rescue by someone in government who "has to know" and who will take care of the problem for us. That may or may not happen. More I ask around, more it seems NOBODY KNOWS about this in government circles!

1) Make your comments! You can mail them in, or you can make them online using the Internet by accessing the ECFS: http://fjallfoss.fcc.gov/ecfs2/ or the Federal eRulemaking Portal: http://www.regulations.gov. Don't just click these links first, though. READ THE FCC PUBLIC NOTICE AND ADHERE TO THEIR GUIDELINES!

2) Write, email, and/or visit your local Senators and Representatives. Danny Lloyd's blog site (People To Write Concerning FCC Docket 10-123) lists how you can do this.

3) Contact the Press,too. If you use EMWIN user (are you an emergency manager? EMWIN sysop or manager? end user of EMWIN who receives bulletins FROM the system? does your University make use of it? your TV station?), let THEM know that we could be losing the EMWIN downlinks. Why not. Couldn't hurt. What's the worst that could happen? Go for it. The more local people who contact their local Press asking them to do a story, the more interested they'll note that people are, and the more likely they'll be to do a story. Contact TV stations, and newspapers big AND small. Tell them how you've been using EMWIN and what good it has done for you. Emphasize it's importance in your community. Hit the NATIONAL networks, too! ABC, CBS, NBC, CNN, MSNBC, Headline News, etc. Again, more we request air time, more likely they will. HIT em!

4) Join listgroups like EMWIN-Users, and WxMesg to keep yourself abreast of the latest.

If you're an ARRL member:

5) Email your Section Managers so that they know what is going on. They can spread the word down into their own sections. (Note: The linked-to page only works for active ARRL members, unfortunately.)

6) Contact the ARRL's Regulatory Information Branch (ARRL Regulatory Information Manager Dan Henderson/N1ND, and ARRL General Counsel Chris Imlay/W3KD). The more who write them, they more they'll think this matters to the hams. The hope is to get thier legal and regulatory departments to look into this and maybe at LEAST suggest ways for us to handle this, or at BEST maybe they'll even jump personally on the bandwagon, themselves.

Some other links on the subject:

- Potential L-band Frequency Sharing - from NOAA-EMWIN Page
- What'sUpWithThat.com - NOAA/GOES Satellite Communications At Risk Due To Proposed Frequency Spectrum Auction. This site gives excellent description of the problem, and how vastly the auction affects things. Use this to educate yourself.
- People To Write Concerning FCC Docket 10-123 - Please carbon copy any correspondance with the Department of Commerce, NOAA or NWS to your Senator and Representive. Because of the short time span, you will want to consider also calling your Senator and Representative.
- StormReady Guidelines - You will notice that EMWIN is the second item listed, with a recommendation to use a satellite dish. The EMWIN service is such a value that it is listed right after NOAA Weather Radio.
- Emergency Management Broadcasting Frequencies - courtesy Zephyrus Electronics, Inc. - This could possibly be used as a starting point to show widespread use of EMWIN across the United States. Could also be used as a contact list to notify these groups of the EMWIN issue and to cooperate and put in their own comments - even if they're no longer "retransmitting", but still use EMWIN for other things. I count some 62 sites in here!

We've been given LESS THAN THREE WEEKS to compose comments and submit them to the FCC. That's kinda ridiculous, but there it is. So let's move on this. Spread the word fast. Compose away people. Join lists such as EMWIN-Users, EMWIN Broadcasters, and WxMesg, too, for more information, and for ideas and suggestions on what to mention in your comments.

UPDATE - 10/11/10: Hard work slowly paying off. We've got word ARRL is a sleeping giant actually researching to make their own response, but they've got a couple of ham-related frequency fights going on that they want to handle, first. As well, NOAA finally issued a PNS bulletin this afternoon acknowledging the EMWIN problem and advised that they too will be submitting a response.

This class is hosted by Columbia County Emergency Services.
Free and open to the public.
Trainees are encouraged to participate as Weather Spotters,
however, continued participation is not mandatory.

What is a Storm Spotter?
The Skywarn spotter program is a nationwide network
of volunteers trained by the National Weather Service (NWS)
to report significant weather. Anyone is welcome to participate.

Why Skywarn ?
The NWS's mission is to protect lives and property.
When weather conditions are favorable for severe thunderstorms
or tornadoes are expected to develop, a severe thunderstorm or
tornado WATCH is issued. A Severe Thunderstorm or Tornado
WARNING is issued when severe weather has been reported by
a Skywarn spotter or indicated by Doppler radar. Skywarn
volunteers become the NWS's eyes and ears, helping to provide
better weather watch and warning services.

Imposter AC-SKYWARN Twitter Account

2010-02-14T16:16:00.005-05:00

Someone has apparently created a duplicate/imposter Twitter account called "alachuaskywarn". This is not our account.

The real Twitter account for Alachua County SKYWARN is "acskywarn" and has a much larger membership base. Unfortunately, some people will not recognize this and will inevitably become confused.

We apologize for this but we have absolutely no control over it. There are some rogue ham radio operators out there who were jealous of how well Alachua County SKYWARN was doing and they went out of their way to try to destroy it. They put on an extremely poor show and went out of their way to stalk, harass, scare and cause harm to myself and a number of my friends, even attacking their careers. They were not successful in destroying the organization itself, or it's web page, or it's web presence. However, they were entirely successful in completely destroying any chance for further SKYWARN spotter training classes inside Alachua County for...well...indefintely. NWS-JAX and ACOEM are too afraid of what the ham radio operators here have been doing here to pursue such a thing for now, and both NWS and ACOEM are rather disgusted. Unfortunately, what happened here in Alachua County has also affected the SKYWARN program across the entire NWS-JAX County Warning Area, as well. Mistakenly thinking that the problem laid with the civilians rather than the hams, NWS-JAX took it out on the wrong program: the civilian spotter program here, rather than the ham radio community. NWS-JAX no longer officially recognizes civilian programs across the ENTIRE County Warning Area. This is gravely unfortunate. This means that spotter classes must now be called for and handled by ACOEM and only ACOEM and since ACOEM is no longer interested in spotter training classes due to what has been happening down here, there will likely be no more spotter training classes for quite a while. The story is long but can be had from here: http://stormspottertodd.blogspot.com/2009/12/where-did-todd-go.html .

They've created imposter Yahoo accounts, too. The real Yahoo account is "ac_skywarn" (the AC-SKYWARN Email Alert List). The imposter account is "AC_Skywarn", which was created by Melissa Royce to deliberately confuse people.

She's also sent me harassing emails before by forging my name in Yahoo and creating an account in my name there, then sending me a harassing email and then deleting the account thinking she'd be hiding the evidence. However, on checking the header information in the email, it pulled up her husband's old personal web page (now no longer existant).

She's not a very bright stalker; but a stalker nonetheless. I suppose she feels very proud of what she does. Everyone take a moment of silence to clap for her in your minds...

(pause)

Okay. Everybody done?

It's unfortunate that I have to deal with people like this. But there yuh go.

(sigh)

Hams/Spotters: Beware Florida Law Regarding Devices Mounted On Windshield

2009-12-07T13:38:00.005-05:00

WARNING FLORIDA DRIVERS:

I had someone advise me today that they got a ticket in November of $116 for having a device mounted upon his windshield. The device was a RADAR-detector, but people should note that detectors themselves are NOT illegal in the state of Florida.

Apparently Florida has had a windshield law which has been around for a while but which has not received much attention...until now. Trying to decipher if this was just an event local to that user or if this is part of a new statewide campaign. (Like the seatbelt law. Been around for a while but not acted on with much ferocity except during a certain specific times of the year. ...Or the laws regarding turning, which are never enforced. You're not supposed to turn wide at intersections if you're turning into a road with two lanes to choose from. But most people do this because there has been ZERO action on enforcement of the law even though it's IN your Florida Driver's Handbook. A lot of accidents could be avoided if cops would actually enforce THAT one - which is a BIGGIE; but they don't.)

At any rate, this would affect things like suction-mounted RADAR-detectors, GPS units, cameras, etc.

Ham radio operators, storm spotters/chasers beware. Hams especially just LOVE to mount things on their windshields, and an expensive law such as this one could destroy a Xmas present (or two, or three) for someone. :(

See the Mobile Scanner & RADAR-Detector Laws home page for more information. I have updated the site with this new information, including the text of the actual law.

Spread the word. Let's not allow anyone's Christmas spirit to be ruined over something like this.

Interesting to note is that the "Television receivers" law (316.303), which prohibits TVs in vehicles, actually exempts "the use of electronic displays used specifically for navigation purposes". But the windshield law would seem to PROHIBIT the very use of those devices anyway, since most all GPS units are suction-mounted! (sigh) ...Legislators. They're SO smart. I'm just...I'm SO proud of them. Aren't YOU?

New series of listgroups: The ACWIN Project...

2009-07-29T11:24:00.003-04:00

ACWIN stands for the "Alachua County Weather Information Network". It is a series of listgroups designed to bring weather bulletins to Alachua and surrounding counties. It will cater not just to Alachua County, but now to other surrounding northern Florida counties as well.

The following counties are included, so far: ALACHUA, BAKER, BRADFORD, CLAY, COLUMBIA, DIXIE, DUVAL, FLAGLER, GILCHRIST, HAMILTON, LEVY, MARION, NASSAU, PUTNAM, SUWANNEE, and UNION.

Each county will have three lists, created to cater to: general weather bulletins, severe weather bulletins, and civil emergency bulletins.

Users will be allowed to subscribe to each bulletin they want individually, without being forced to take everything we offer at once.

Before, users in surrounding counties were on their own. Alachua County had a SKYWARN program, and a bulletin distribution system which catered to them; but the surrounding counties had nothing, because they were smaller and there just wasn't any interest or support. We've tried to help them out by supporting them. That is what this new suite of email lists is designed to do.

For more information about the ACWIN Project, see alachuaskywarn.org/acwin .

New means of subject line handling in listgroups...

2009-07-29T11:23:00.002-04:00

Working with Danny Lloyd this week, I convinced him to add a new feature to WxMesg software which allows concurrent use of both Product identifier abbreviation and full product name in the subject line. Before this, subjects either had to use the product name only (such as "ZFPJAX") or the full product name (such as "Zone Forecast Product"), but they couldn't do both at the same time. This new feature facilitates listgroup usage. Now we can send bulletins that can be sorted by the "topic" name (which happens to be the product identifier, such as ZFPJAX), while still identifying the bulletin. For example:

"ZFPJAX: Zone Forecast Product"

The listgroups are only concerned with finding that topic name in that subject line. That is, they hunt for the topic name in the first few characters of the subject. Once found, anything AFTER that is ignored. So we can get away with adding the full bulletin name after the "topic"/product identifier. Note that we were even able to throw in a colon (":") after the product ID. :)

We can also include product/watch/warning issuance/expiration times, now, if we want to. Example: "ZFPJAX: Zone Forecast Product [00:00Z - 08:00Z]". For right now, this feature will only be used, however, for special situations.

This new feature is now being utilzed in both the ACEMWIN-HURR-L and ACWIN-* listgroups.

HUGE New Changes To ACEMWIN-HURR-L Hurricane Bulletins List

2009-07-10T20:52:00.009-04:00

The ACEMWIN-HURR-L list was created on July 16, 2005, The list serves the latest hurricane bulletins to the public. Yesterday, after many weeks of researching Listserv and EMWIN software documentation, major changes were finally implemented to the listgroup, now allowing users to pick and CHOOSE which hurricane bulletins they want. Before, users were forced to have to receive them all. When the season got busy, the listgroup would often end up ovewhelmed. No longer. Using a Listserv software feature called "topics", users may now turn on or off bulletins at thier own WILL. Users will greatly appreciate this new capability.

The list receives the latest hurricane-related bulletins from the Alachua Co. EMWIN Project's EMWIN server. The EMWIN server receives weather bulletins hot off of the GOES-10 weather satellite located high above the earth in geosationary orbit. As soon as weather bulletins are issued by NOAA, the NWS, the SPC, the NHC, and other various weather centers, they are immediately transmitted to the satellite, and then bounced back down to the earth for other ground stations to receive. The Alachua County EMWIN Project owns such a ground receiving station. Whenever the NHC issues hurricane related bulletins, they will appear in this list as soon as they are sent down from the satellite. Subscribers to this list will receive Atlantic-region hurricane-related bulletins.

Testing of the new changes is complete and everything seems to be working fine, and the listgroup is again ready for public use.

Here are the "topic" areas that are now available to choose from within the ACEMWIN-HURR-L listgroup:

PWSAT: Tropical Cyclone Surface Wind Speed Probabilities
SPFAT: Storm Strike Probability Bulletin
TCANT: Tropical Cyclone ICAO (Aviation) Advisory
TCDAT: Tropical Cyclone Discussion
TCEAT: Tropical Cyclone Position Estimate
TCMAT: Marine/Aviation Tropical Cyclone Forecast/Advisory
TCPAT: Public Tropical Cyclone Advisory
TCPSP: Public Tropical Cyclone Advisory (spanish)
TCUAT: Tropical Cyclone Update
TCVAT: Tropical Cyclone Watch/Warning Product (VTEC)
TWDAT: Tropical Weather Discussion
TWOAT: Tropical Weather Outlook and Summary
TWSAT: Monthly Tropical Weather Summary
CHGHUR: Tropical Cyclone Objective Guidance
STDCCA: Satellite-derived Trop. Disturbance Summary (C. Carribean)
STDECA: Satellite-derived Trop. Disturbance Summary (E. Carribean)
STDWCA: Satellite-derived Trop. Disturbance Summary (W. Carribean)

All new users are automatically subscribed to ALL of the above bulletins. However, you can turn some OFF at any time if things seem to get just a little too "busy" for you.

For a detailed description of each of the above bulletins, see the NHC's Text Products Description page at http://www.nhc.noaa.gov/aboutnhcprod.shtml.

Another new addition to the listgroup is the archiving feature. The listgroup is now being archived. This means that users can now also peruse past hurricane bulletins. To view these archives, see: http://lists.ufl.edu/archives/acemwin-hurr-l.html.

ACEMWIN-HURR-L IS A READ-ONLY LIST. In other words, users may not post to the list. This list is for the dissemination of hurricane-related bulletins only. The list owner/moderator is Todd Sherman (acemwin@alachuaskywarn.org).

For more information about the listroup, see http://alachuaskywarn.org/emwin/acemwinhurrl.

Created Alachua County EMWIN Project Blogspot Blog and Twitter Feed

2009-06-04T11:07:00.006-04:00

Created a Blogspot for the Alachua County EMWIN Project, which sends weather-related bulletins to local area people for free as a public service. AC-EMWIN sends bulletins to email, cellphone, pager, and even web sites. This blog will be used to let people know the status and progress of the Alachua County EMWIN Project.

Also created a Twitter account for AC-EMWIN. This now allows us to send local area (Alachua County) bulletins to Twitter for those who like to use that.

The AC-EMWIN Blog is at http://acemwin.blogspot.com/.
