CMAS/WEA and IPAWS
CMAS/WEA is a free public mobile alerting service that targets your current location using radio like technology
3
IPAWS is a national alerts aggregator run by FEMA that feeds CMAS/WEA and other alerting channels
An experimental SMS text message alerting service for community decision leaders. You get alerts for the areas you’ve subscribed. iNWS is independent of WEA and IPAWS.
iNWS
WEA
iNWS • Available to community leaders • Alerts for user defined areas • Includes link to graphic and full text • SMS subject to network congestion • Still experimental
WEA • Available to general public • Alerts for your current location • No graphics or full text • Not subject to network congestion • Cemented in FCC regulations • Cell broadcast bleed-over can
cause false alarm for some

iNWS and WEA Serve Different Purposes

Where to get CMAS/WEA
• Built-in on newer cell phones – About 10 to 40 devices per major carrier – May be called wireless alerts, CMAS, or
government alerts (iPhone)
• Available on Google Play for some

Wireless Emergency Alerts (WEA) Alert Categories • Presidential • Imminent threat to life and property (e.g.,
severe weather, HazMat, earthquake) • AMBER Alert/child abduction Opt-out/in differences between cell phones • Many droid phones break out imminent threats
into two categories- Extreme and Severe • Can opt out of Severe and still get Extreme

Extreme Severe Tornado Warning Extreme Wind Warning Tsunami Warning* Hurricane/Typhoon Warnings
Flash Flood Warning Dust Storm Warning Blizzard Warning Ice Storm Warning
*Tsunami Warnings coming to WEA later in 2013

*When new alert or correction issued or time/area extended*
Quick Facts about WEA • Purpose to notify (i.e., a bell ringer), recipient should seek details from traditional sources
• Is a free opt-out service
• Uses cell broadcast technology – Merely a radio broadcast, so the service doesn’t track you – Alerts not subject to network congestion as with traditional text messaging
• Major carriers are committed to producing WEA capable phones
• If you travel into an alert area after the alert was originally sent, you should still receive it
• Each WEA is only displayed once, so you don't receive duplicates
• WEA has a distinct vibration cadence and audio tone
• Alerts do not interrupt when you are in a voice or data session on the device

WEA During Sandy/Superstorm
NWS • 4 Flash Flood Warnings
• 13 Blizzard Warnings
• No Hurricane Warnings – High Wind Warnings issued, but don’t currently trigger WEA – Expect Service Assessment to being conducted (common when big storm)
12
NYC OEM • “MANDATORY EVACUATION Zone A, Rockaways, Hamilton Bch, City Is. 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 9-1-1 for emergencies only.”
WEA Feedback Successes • WEA messages received within seconds of warning issuance • Generally favorable feedback in big cities along east coast • Elmira, NY (July 26) - Tornado with 10 mile path, 2000 structures damaged,
people sheltered in response to WEA, no major injuries • Orlando, FL (Dec) - Tornado hit 60+ mobile homes, only 2 injured • Indiana (June 29 Derecho) - WEA alerted people of tornadoes in Indiana when
NWR was down
Opportunities for improvement • Bleed-over in rural areas where cell tower may broadcast to larger area • Pack more information into the 90 character message
Jury is still out on some warning types over WEA • Blizzard and ice storm • Flash Flood

Carrier TargeDng of the WEA Broadcast
• FCC reg says carriers can broadcast to county (towers 1-6), even if alert only at sub-county level
• As of 2/7/13, all major carriers target sub-county (a good thing) when sub-county alerts are issued - Some carriers broadcast from cell towers within sub-county alert area (towers 2 and 3) - Some also broadcast where signal overlaps sub-county alert area (adds towers 1 and 4)
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
• Media interviews, school and government officials, community events, PSAs, etc.
• CTIA links to WEA information for each major carrier at ctia.org/wea
• NWS FAQ at weather.gov/wirelessalerts
• Cell users should contact their carrier regarding WEA capability, to report issues, or seek assistance
