Subject:  Warnings Starting to Roll Out on Wireless

          Emergency Alerts


Today, the most critical NWS warnings will begin triggering

Wireless Emergency Alerts (WEA) on WEA-capable cell phones.  


NWS produced Common Alerting Protocol (CAP) messages are pushed

to the Federal Emergency Management Agency (FEMA) Integrated

Public Alert and Warning System (IPAWS).  These messages are

formatted to trigger a WEA broadcast for the following types

of NWS warnings.


- Tornado Warnings

- Flash Flood Warnings

- Hurricane and Typhoon Warnings

- Extreme Wind Warnings

- Blizzard and Ice Storm Warnings

- Dust Storm Warnings


Through the summer, the NWS will be working to enable the

triggering of WEA for Tsunami Warnings.

Wireless carriers began rolling out the WEA service across

the nation on April 7, 2012.  All major wireless carriers and

hundreds of smaller carriers are taking part in WEA on a voluntary

basis.  To find out if your phone will get these messages, contact

your wireless carrier or check the link below:
