Severe Weather from NOAA/NWS

National Weather Service (NWS) Alerts are emergency messages sent by authorized government alerting authorities through your mobile carrier. Government partners include local and state public safety agencies, FEMA, the FCC, the Department of Homeland Security, and the National Weather Service.
Why is this important to me?
Imagine this: You’re driving down the highway, humming along to your favorite tunes, when the cell phone stowed in your bag suddenly makes a strange noise. To investigate, you take the next exit and safely pull over to check the screen. Good thing you did: Your phone just alerted you to a tornado a few miles away in same county you’re driving through.
Sound plausible? It is. America’s wireless industry is helping to build a Weather-Ready Nation through a nationwide emergency alert system, which will warn you when weather threatens.
Alerts received at the right time can help keep you safe during an emergency. With NWS Alert, alerts can be sent to your mobile device when you may be in harm's way.
What types of alerts will I receive?
Extreme weather warnings
Local emergencies requiring evacuation or immediate action
AMBER Alerts
Presidential Alerts during a national emergency

The NWS Alert message will typically show the type and time of the alert, any action you should take, and the agency issuing the alert. The alerts will also provide GPS and map for detail guide .
