First Polygon Siren Activation in Alabama

Dadeville, Alabama – November 30, 2010 – Weather Message Software reported the first polygon siren activation in the state of Alabama.  The automatic siren activation occurred today in Autauga County. 

At 9:15 am, the National Weather Service issued a tornado warning for the Northwest corner of Autauga.  The Weather Message Siren Controller received the tornado warning, decoded the polygon information, and activated four sirens.

Autauga County has a population of approximately 50,000 people.  With over 30,000 located in the City of Prattville.  Rocky Millman, Autauga County Emergency Management Director, installed Weather Message’s Siren Controller in February 2010.  His mandate was to activate only the sirens in areas affected by storms.

For the siren activation today, only four sirens out of the twenty-seven were activated.  The residents of Prattville were not affected by the storm and their sirens were not activated.  The activation of sirens has a direct impact on the County’s economics.

American Meteorological Society's Emergency Management Committee seeks feedback on proposed radio spectrum sharing; response date extended to Feb. 17, 2015
Bob Goldhammer, CEM, IAEM-USA outreach liaison and co-chair of the American Meteorological Society's (AMS) Emergency Management Committee, requests feedback from users of the Emergency Managers Weather Information Network (EMWIN) system who receive their data directly via satellite broadcast. The assured availability of EMWIN over the air reception may be diminished or constrained due to planned or proposed radio spectrum sharing. The radio spectrum just above EMWIN was sold by auction this month to the commercial broadband wireless community, and regulators are evaluating whether to offer the radio spectrum that includes EMWIN for a future commercial auction. Both actions could create significant interference for EMWIN users. If you use EMWIN, please provide your responses to the following three questions via email to by Feb. 17, 2015, using the email subject line "EMWIN Usage Response." If you submitted comments and have received no response from Bob Goldhammer, please re-send your information.

1. Do you or your organization receive EMWIN broadcasts? If so, please provide your organization's name, city, county and state where EMWIN receiver(s) are located.
2. Please briefly cite one example of when/how EMWIN played a significant role in a past EM event, or tell us how you currently use EMWIN received via satellite.
3. If you use EMWIN, please indicate what population area is served by this data, including any retransmission or further near-real time use of this data (e.g., King Country, WA or Tri-County area of Sevier, Piute and Wayne, UT).
