Free tornado, flood & severe weather alerts — plus the only weather app with real USGS river flood gauge monitoring built in. Built for people who take weather seriously.

Every data source is official and free — National Weather Service, USGS, National Hurricane Center, AirNow, and NOAA. No paywalls on safety features. Ever.

⚠️ SEVERE WEATHER ALERTS
Get tornado warnings, flood watches, winter storm advisories, and every other NWS alert type pushed to your phone within seconds of being issued — even when your screen is off. View full alert details including onset, expiration, and affected areas. Alert history keeps 7 days on record.

🌩️ LIVE WEATHER RADAR
Animated NWS composite radar with 20-frame playback. Play, pause, and scrub through storm movement. Active NWS alert polygons overlaid on the map so you see exactly where warnings are in effect.

🌊 RIVER LEVEL MONITORING & FLOOD ALERTS
Track water levels at over 12,700 USGS river gauges nationwide on an interactive map. Gauges are color-coded by NWS flood category — normal, action, minor, moderate, major. Get push notifications when your river crosses into a new flood stage.

🌀 HURRICANE TRACKER
Monitor active Atlantic and Pacific tropical storms and hurricanes with real NHC forecast tracks, wind speed, pressure, storm category, and GOES satellite imagery. Get notified when a storm forms, intensifies, or comes within 500 miles of you.

📻 EMERGENCY SCANNER RADIO
Listen to live police, fire, EMS, and weather radio scanner feeds directly in the app. Add any stream URL — if your local scanner has a feed, StormCast can play it.

🔥 FIRE WEATHER CONDITIONS
Local fire danger rating with Red Flag Warning monitoring. Know when wind, humidity, and temperature combine to create dangerous fire conditions in your area.

🌍 EARTHQUAKE ALERTS
Real-time USGS earthquake monitoring with push notifications based on magnitude and distance from your location. M2.5+ quakes checked every 10 minutes.

🌌 SPACE WEATHER & AURORA ALERTS
Live Kp index, geomagnetic storm notifications, CME arrival tracking, NOAA SWPC alert banners, and Northern Lights visibility guidance based on your latitude.

😷 AIR QUALITY ALERTS
AQI monitoring with push notifications when air quality reaches unhealthy levels in your area.

📍 WEATHER DASHBOARD
Current conditions at a glance: temperature, feels-like, wind, humidity, pressure, UV index, air quality, sunrise/sunset, rain nowcast, 7-day forecast, and an Outdoor Activity score.
