(KFVS) - The American Red Cross will launch its official Tornado App on Monday, March 4.

The Red Cross says the app will put lifesaving information right in the hands of people who live in, visit or have loved ones in tornado-prone areas.

The free app, available in English and Spanish, gives iPhone, iPad and Android smart phone and tablet users instant access to local and real-time information, so they know what to do before, during and after a tornado. The app includes a high-pitched siren and "tornado warning!" alert that signals people when a NOAA tornado warning has been issued in their area, even if the app has been closed. An "all clear!" alert lets users know when a tornado warning has expired or has been canceled.

Viewers sent us these pictures Thursday, February 21 of the winter weather in their area.

(KFVS) - Registration for the 2013 Great Central U.S. ShakeOut is still open.

The next ShakeOut will take place on Feb. 7 at 10:15 a.m. Organizers say this date coincides with the anniversary of the Feb. 7, 1812 earthquake near New Madrid, Mo. They say this earthquake was one of at least three magnitude 7 or greater events that struck in the winter of 1811-1812, and forever changed the landscape of the region.
