The World Meteorological Organization put out its strongest El Niño warning yet, giving near-certain odds of the pattern holding through February 2027. That means more intense storms, deeper heat waves, and busier hurricane seasons in the Atlantic and eastern Pacific. A weather widget is not enough. The best storm-tracking apps push severe alerts before you would notice the sky change, show radar animations that let you time a run for shelter, and work when the cell towers get busy.
We tested eight Android apps that focus on severe weather rather than daily forecasts. Each is judged on speed of alerts, radar resolution, and how well it works when service is patchy.
What to look for in a severe storm app
- NOAA/national weather service alerts. Government alerts are the source of truth. The best apps push them within seconds.
- High-resolution radar with animation. A 10-minute loop tells you which cells are moving toward you.
- Lightning strike map. Real-time strike density is a reliable proxy for a storm’s intensity.
- Hurricane and tropical storm tracking. During El Niño years, tropical storms in some basins get busier.
- Widget and lockscreen alerts. You should not have to open the app to see a tornado warning.
- Offline caching. When the storm arrives, so does packet loss. The app should show the last good radar frame.
- Low ad load. Free severe-weather apps sometimes bury the “safe” info under video ads.

The apps
1. MyRadar Weather Radar — Best overall radar and alert app
MyRadar puts an animated NEXRAD radar in front of everything else. Tropical storm cones, wildfire smoke plumes, aviation layers, hurricane tracks, and severe weather warnings can all be turned on as overlays. The alert system taps NWS directly, so tornado warnings and severe thunderstorm warnings push within seconds. On the Pro tier you get lightning strike detection, hurricane forecast paths, and no ads.
Where it falls short: the base app is generous, but full lightning coverage is behind Pro. Battery use with animated radar left on is noticeable.
Pricing:
- Free: radar, alerts, tropical cones
- Paid: Pro with lightning, hurricane detail, ad-free
Platforms: Android, iOS, Windows
Download: Aptoide, Google Play
Bottom line: the best default choice for anyone in the US who wants strong severe alerts without paying.
2. Windy.com — Best forecasting and model access
Windy.com exposes global weather models (ECMWF, GFS, ICON, and others) inside a beautifully readable interface. Layers include wind, precipitation, temperature, waves, and a lightning tracker driven by the Blitzortung network. You can compare model outputs side by side, which is how meteorologists and pilots use it. Severe storms are visible days out in the model animations, not just when they hit.
Where it falls short: it is a forecast tool first, so alert pushing is less aggressive than MyRadar’s. Set NWS notifications inside settings.
Pricing:
- Free: full map, most layers
- Paid: 1-hour update interval and higher-resolution models
Platforms: Android, iOS, Web
Download: Aptoide, Google Play
Bottom line: the strongest planning tool. Pair with MyRadar for alerts.
3. AccuWeather — Best minute-cast and severe watch coverage
AccuWeather built its reputation on granular short-range forecasting. MinuteCast tells you when the rain starts and stops on your exact street. Severe weather alerts include national-service warnings plus AccuWeather’s own experimental forecast bulletins. RealFeel numbers, humidity, and wind all update every minute during active weather.
Where it falls short: the free tier has aggressive interstitial ads. RealFeel numbers can differ from official records by a wide margin.
Pricing:
- Free: full basics
- Paid: ad-free, extended radar, no interstitials
Platforms: Android, iOS, Windows, macOS
Download: Aptoide, Google Play
Bottom line: the pick for anyone who wants sub-hourly precision.
4. RadarScope — Best pro-grade radar for storm spotters
RadarScope shows the same dual-polarisation radar data storm chasers and NWS forecasters use, without smoothing or interpretation. You get base reflectivity, velocity, correlation coefficient, and storm-relative motion, plus tornado vortex signature and mesocyclone markers. If you spot storms, this is the app.
Where it falls short: overkill for casual users. The interface assumes you know what dual-pol data is.
Pricing:
- Free: 15-day trial
- Paid: one-time purchase for the base app, subscription for premium features
Platforms: Android, iOS, macOS, Windows
Download: Google Play
Bottom line: the pick if you have ever said “the app shows red, but is that a rotation”.
5. Weather Underground — Best hyperlocal accuracy
Weather Underground aggregates data from over 250,000 personal weather stations, so its conditions map is more granular than any satellite-derived service can produce alone. The severe alerts include NWS content, and the Storm Live viewer shows lightning, cell velocity, and rotation on a fast-scrolling map.
Where it falls short: the free app is heavy with ads. Some interface habits still show its long, complicated history.
Pricing:
- Free: full basics with ads
- Paid: ad-free and extended maps
Platforms: Android, iOS
Download: Google Play
Bottom line: the pick if you have a Weather Underground station on your street, or want the hyperlocal read.
6. The Weather Channel — Best for interactive maps and video briefings
The Weather Channel app is the mobile arm of a full broadcast operation, and it shows. Severe weather coverage during an active event includes live video briefings, expert commentary, and continuous map updates. The severe-weather-only alert channel can be enabled without opting into all push notifications.
Where it falls short: the free tier has the same aggressive ad load as AccuWeather. Video briefings are streaming-heavy on cellular.
Pricing:
- Free: full basics with ads
- Paid: Premium removes ads and adds professional maps
Platforms: Android, iOS
Download: Google Play
Bottom line: best if you want an expert to tell you what the radar means during a hurricane landfall.
7. NOAA Weather Radar Live — Best minimal NWS-only app
NOAA Weather Radar Live stays deliberately simple. National Weather Service alerts come through with source attribution, hourly and daily forecasts sit on one screen, and the radar loop is the standard NEXRAD product without extra branding. Widgets are small and reliable. If you want a straight window into NWS data, this is it.
Where it falls short: limited to US NWS content. International users should pick Windy or Weather Underground.
Pricing:
- Free: full basics
- Paid: annual subscription for ad-free and extended history
Platforms: Android, iOS
Download: Google Play
Bottom line: the cleanest pick if you live in the US and just want NWS data with no upsell.
8. Storm Radar — Best focused storm-only tracker
Storm Radar was built by The Weather Channel’s team specifically for storm season. It cuts everything except radar, alerts, and forecast tracks. Multi-day loops let you see where a system is heading; hourly precipitation type shows the freezing-rain and snow transitions that break drives home.
Where it falls short: it deliberately drops non-storm data. You will still need a general forecast app on quiet days.
Pricing:
- Free: full basics with ads
- Paid: Pro removes ads and unlocks extended radar
Platforms: Android
Download: Google Play
Bottom line: the pick if you want a stripped-down storm app and nothing else.

FAQ
What is the best severe storm app for Android? MyRadar for most people. Windy for planners and pilots. RadarScope for spotters.
Do free weather apps push tornado warnings fast enough? Yes, if they tap NWS directly. MyRadar, Weather Underground, and NOAA Weather Radar Live all do. Set the alert channel to high priority so it bypasses do-not-disturb.
Which apps work outside the US? Windy.com and AccuWeather cover the globe with model data. Local national services (Met Office, ECMWF, JMA) are the source of truth in their regions.
Does El Niño mean more tornadoes? Not directly. El Niño tends to shift the jet stream, which can suppress Atlantic hurricanes but increase severe weather in parts of the US Gulf and Southeast, and heavier winter storms in California.
Should I keep two weather apps installed? Yes. Most storm-tracking pros keep one radar-first app (MyRadar or RadarScope) and one model-first app (Windy) side by side.
