StormCast: Weather & Radar

Tornado, flood and severe weather alerts, with USGS river gauge monitoring and flood alerts built right in. Made for people who take weather seriously.

⚠️ SEVERE WEATHER ALERTS
Tornado warnings, flood watches, winter storm advisories and every other NWS alert type, pushed to your phone fast, even with the screen off. Each alert shows when it starts, when it ends and the areas it covers, and your recent alert history is always there to look back on. Get alerts for home, work, family and wherever you are right now.

🌩️ LIVE WEATHER RADAR
Animated radar with play, pause and scrub controls. Active warnings are drawn right on the map so you can see exactly where they’re in effect. Tap one to read it.

🌊 RIVER LEVELS & FLOOD ALERTS
Track water levels at thousands of USGS river gauges on an interactive map, color-coded by NWS flood category: normal, action, minor, moderate and major. Get notified when your river reaches a new flood stage or starts rising fast.

🌀 HURRICANE TRACKER
Follow Atlantic and Pacific storms with NHC forecast tracks, wind speed, pressure, category and satellite imagery. Get notified when a new storm forms or strengthens.

⚡ LIGHTNING ALERTS
Know when lightning is striking near you.

🏘️ NEIGHBORHOOD REPORTS
See and share what’s happening near you, like downed trees, power lines and flooding, and get notified about severe reports in your area.

🌌 SPACE WEATHER & AURORA
A full space weather center: tonight’s Northern Lights chances for your exact location, your sky conditions (clouds, moon and darkness), NOAA storm watches and bulletins, live aurora maps, webcams and a beginner’s guide. Geomagnetic storm alerts, plus optional aurora alerts when a storm is strong enough to see from where you are.

🌍 EARTHQUAKE ALERTS
Notifications for USGS-reported earthquakes near you.

❄️ SNOW ALERTS
A heads-up when snow is on the way.

🔥 FIRE WEATHER
Local fire danger and Red Flag Warnings, so you know when wind, humidity and temperature line up for dangerous fire conditions.

😷 AIR QUALITY
Alerts when air quality reaches unhealthy levels where you are.

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