As many as 26 tornadoes ripped through Oklahoma, Kansas, Illinois and Iowa today, with Oklahoma City hardest hit.
This was the second time this month a tornado hit Oklahoma City and the National Weather Service warns that millions are still at immediate risk for severe weather, from Texas to the Great Lakes. It is tracking storms moving eastward as far as the Gulf Coast and Northeast on Tuesday and Wednesday.
One way to protect yourself is to download an app that can warn you when a tornado is spotted in your area. Here's a list of apps that can help:
Tornado from the American Red Cross
This free app is available in English or Spanish for the iPhone and Android. It sounds a siren when an official tornado warning has been issued and sends an all-clear signal when the warning is over. Some content is preloaded so users have information even if the phone lines go down, such as where Red Cross shelters are located. It also includes a preloaded, one-touch “I’m safe” message.
The Weather Channel app from the Weather Channel

TornadoSpy+ from By Justin Time
The $2.99 TornadoSpy+ iPhone and iPad app sends alerts and shows weather on radar maps. It also lets users upload crowdsourced info about tornadoes and other dangerous weather in their areas. Its makers say that on May 10, a user spotted the Oklahoma City tornado 20 minutes before the NOAA report, which meant other users had more time to protect themselves.
