NWS Warnings Activating WEA(Approximate) Severe Weather Season
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
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
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

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
