  1. Wireless Emergency Alerts

    Michael Gerber NOAA/National Weather Service Silver Spring, MD NWS Partners Meeting August 5, 2013
  2. Overview NWS WEA activation Statistics and feedback Examples of lives saved Opportunities to improve Getting the word out
  3. WEA Messages Originated by NWS Legend tzT = timezone ddd= three letter abbreviation for day of the week
  4. NWS Warnings Activating WEA(Approximate) Severe Weather Season
  5. WEA Credited with Saving Lives WEA messages received within seconds of warning issuance Elmira, NY (July 26, 2012) – 10 mile tornado. 2000 structures damaged. No major injuries. Adairsville, Georgia (Jan 29, 2013) –Vehicles stopped on I-75. Watched tornado cross highway. Jefferson Co, MS (Feb 21, 2013)– Woman looked outside and saw tornado backlit by lightning. Family got in the bathtub. Tornado heavily damaged bedroom where they would’ve been sleeping. Yell and Pope County, Arkansas (Apr 10, 2013) – “I would have drove right into it. I was able to stop and keep others at the store from driving into it with the info from the alert. Despite limited cell service, I received cell alerts and was able to take cover in Jessieville and avoid driving into the brunt of the storm.” – Red Cross Emergency Manager East Windsor, CT (July 1, 2013) – Up to 34 lives saved (29 children). Tornado WEA prompted soccer dome manager to evacuate everyone. Seconds later, dome thrown high above highway. Warning: Extreme language in this video
  6. Opportunities for Improvement Hone in on optimal WEA activation to minimize alert fatigue/opt-outs Current NWS activation by event type, but exploring options which allow flexibility with flash floods, blizzards, ice storms, dust storms, etc. Consistency- Android users can opt-out of severe and still get extreme WEA, but not iPhone NWS to participate in new FCC Federal/industry working group on WEA Better convey actual warning area to WEA for NWS zone based warnings WEA targeting counties (FIPS), since WEA only understands FIPS, polygons, and circles Polygons would be optimal Derechoservice assessment recommends activation for extreme thunderstorms Android iPhone
  7. Getting the Word Out Set realistic expectations – WEA Is a bell ringer, not a replacement for traditional warning systems Create one-page web/social media/handout preparemetrokc.org/WirelessEmergencyAlertFlier.pdf New Ready/FEMA /Ad Council PSAs :30 Spot: http://www.youtube.com/watch?v=K9U_iOYx3aM :15 Spot: http://www.youtube.com/watch?v=y-btLGsjQYc Spanish Version: http://www.youtube.com/watch?v=iltPObaagWk CTIA links to WEA information for each major carrier at ctia.org/wea NWS FAQ at weather.gov/wirelessalerts Contact your wireless carrier for more information
  8. WEA PSAs Launched May 2013 FCC allows broadcast or transmission of a simulated WEA in PSAs developed by FEMA. http://transition.fcc.gov/Daily_Releases/Daily_Business/2013/db0531/DA-13-1301A1.pdf 15 second spot 30 second spot Spanish 30 second

  12. WEA is a bell ringer and doesn’t replace other alerting systems While WEA is new, early results are promising as lives saved Occasional hiccups and opportunities to improve, service evolving “Big Four” carriers performing better than required by the FCC regulations by geotargeting WEA broadcasts at the sub-county level More work needed by all partners to get the word out about WEA
