Subject:  NWS Capable of Activating Wireless Emergency Alerts for

          Tsunami Warnings Effective January 31, 2014


As of Friday, January 31, 2014, NWS is capable of activating Wireless

Emergency Alert (WEA) capable cell phones for the most critical Tsunami

Warnings. With this capability, NWS will activate WEA for Tsunami Warnings

in situations where a Tsunami Watch or Tsunami Advisory was not

previously in effect.


This capability is a first step toward enabling WEA activation for all

Tsunami Warnings by May 2014.       


On June 28, 2012, NWS began disseminating its most critical warnings to the

Federal Emergency Management Agency (FEMA) Integrated Public Alert and

Warning System (IPAWS) for broadcast on WEA capable cell phones.


The NWS also activates WEA for:


- Tornado Warnings

- Flash Flood Warnings

- Hurricane and Typhoon Warnings

- Extreme Wind Warnings

- Dust Storm Warnings


NWS is also developing future capabilities that will allow activation of WEA

for weather and hydrologic events based on expected event impact rather than

by warning type alone.  


All major wireless carriers and hundreds of smaller carriers are taking part

in WEA on a voluntary basis. To find out if your phone is WEA-capable or

if you have other questions related to the receipt of WEA on your cell phone,

please contact your wireless carrier or check the link:
