Every NWS Warning Type
Tornado Warning, Severe Thunderstorm Warning, Flash Flood Warning, Flood Watch, Winter Storm Warning, and every other official NWS alert — delivered the moment it's issued for your area.
WHAT MAKES IT DIFFERENT
Every NWS warning, nothing muted.
One of the fastest refresh rates of any weather app, for every official NWS alert type.
Checked Every 30 Seconds
StormCast polls the NWS alert feed every 30 seconds — one of the fastest refresh rates of any weather app — so life-safety warnings reach you with minimal delay.
Life-Safety Alerts Can't Be Muted
Tornado, flash flood, and other life-safety warnings always deliver — they're never affected by Quiet Hours, so a warning at 3 AM still reaches you.
More Than Just Weather Alerts
StormCast also monitors 12,700+ USGS river gauges, tracks hurricanes with GOES satellite imagery, and delivers earthquake, air quality, and aurora alerts — one app instead of five.
