Stormkeeper: Tornado Tracker Live

Know in two seconds if you're safe. Stormkeeper is a free tornado tracker and weather radar for the United States. It reads official National Weather Service alerts and tells you plainly: safe, watch, warning, or take shelter now. ONE CLEAR ANSWER • Open the app and see your status first, then the radar that backs it up • Official alert text from the National Weather Service, never rewritten HOW FAR, HOW LONG • When a storm is heading your way, see its distance, direction and the minutes until it reaches you • A "Take shelter now" screen with your own shelter plan and a countdown until the warning expires • An all clear when the warning has ended, so you are not left guessing WATCH OVER FAMILY • Save up to 3 places, like a parent's town or a school, and see the status of each one MORE THAN TORNADOES • Severe thunderstorm and flash flood warnings, and watches • Lightning near you, with the 30/30 rule countdown • Live NOAA radar with a timeline you can replay • Today's storm risk from the Storm Prediction Center, in plain words • Hourly forecast, open shelters nearby from FEMA and the Red Cross, and short safety guides • English and Spanish FREE, WITH RESPECT • Radar and official alerts are free • The app shows ads, but never while a watch or warning is active for your location, and never on the "Take shelter now" screen • No account needed IMPORTANT Stormkeeper checks for new alerts while the app is open. It does not replace outdoor sirens, Wireless Emergency Alerts on your phone, or a NOAA Weather Radio. Alerts can be delayed by your network or device. When a warning is issued for your area, act on it. Coverage: the United States and its territories. The app relies on US government weather data, so it does not work elsewhere. Data: alerts and forecasts from the National Weather Service; radar and lightning from NOAA; storm outlooks from the Storm Prediction Center; maps from OpenStreetMap contributors. Stormkeeper is not affiliated with NOAA or the National Weather Service.
