NYC.gov or 311 for details” – “Emergency Alert in this area until 8:00 AM GMT Take Shelter Now NYC_OEM” – Go indoors immediately and remain inside. DO NOT DRIVE. Call 91-1 for emergencies only. 12 MESSAGE CONTENT Use of polygon to describe threat area • Increase value and relevance of warning • Compared to warning by county, polygon warnings can reduce warned area by 70% to 97%, especially in Western U.S. • NWS started using polygon warnings October 1, 2007 • • • • • • • Tornado Warnings (trigger WEA) Flash Flood Warnings (trigger WEA) Severe Thunderstorm Warnings Special Marine Warnings Severe Weather Statements Flash Flood Statements Marine Weather Statements 13 Originator Proficiency • Online Training (FEMA Course IS-247) – Introduction to system – Appropriate, Effective, and Accessible Alert and Warning Messages – Common Alerting Protocol Message Composition • Practice and Drill 14 Regular Testing • Test processes in a test environment – Both NWS and FEMA have test environments that process real data all the time • Validate system response is as expected IPAWS 15 Conduct Outreach • 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 • Media interviews, school and government officials, community events, Public Service Announcements • Government agency and industry association links to outreach information for each major carrier – example: www.ctia.org/wea) • Develop FAQs – example: www.weather.gov/wirelessalerts • Cell users should contact their carrier regarding WEA capability, to report issues, or seek assistance 16 Monitor Feedback • Social media • Call centers • Family and friends • Calls and emails to originating authority 17 Current and Future Plans • NWS CAP messages now being disseminated via two satellite systems in parallel with traditional text alerts • Newest version will soon be on NWS websites via ATOM index feeds • Better descriptive language of impacted areas • Allow originating meteorologist to custom tailor message 18 Summary • NWS has been using CAP to send short messages to cell phones located in impacted areas since June 2012 • Early results are positive with some affected citizens crediting system to saving lives • Lessons learned center less around the technology and more around the message content and public outreach 19
