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

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

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

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:

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 (
