As technology improves, one has more ways to acquire severe weather warnings issued by your local National Weather Service (NWS) Forecast Office. You can add mobile device alerts from the National Weather Service to that list. However, a number of commercial TV stations have provided cell phone alerts for several years.
The NWS's primary mission is to issue severe weather watches and warnings that minimize the loss of life and property.
It is important for one to have multiple methods of receiving warning information - whether it be outdoor sirens, commercial television and/or radio, cable TV, NOAA Weather Radio All Hazards, cell phone alerts, and other computer-sent related warning information. Hopefully, one of these methods will be appropriate for your current situation - whether it be indoors, outside, or on the road.
Even though Commercial Mobile Alert system (CMAS) and Wireless Emergency Alerts (WEA) functionality is currently "turned-on" in the mobile device environment, selected NWS weather-related warnings will not be sent to CMAS-WEA until sometime in June, 2012.
