WeatherAlarm watches your saved locations 24/7 and sends you a push notification the moment a warning or dangerous outlook is issued.
Features
WeatherAlarm is focused on one job: making sure you know when severe weather is headed toward someone you care about.
Monitor Mom, Dad, Grandma, and anyone else — each labeled with a name you choose, not just an address.
Instant alerts for tornado warnings, severe thunderstorm warnings, winter storms, floods, and dozens of other NWS products.
Know when a location enters a Marginal, Slight, Enhanced, Moderate, or High risk area before storms even develop.
Alerts arrive directly on your iPhone — no need to open the app or watch a radar. You'll know the moment something changes.
Install on multiple iPhones and your saved locations automatically sync across all of them via iCloud.
No account sign-up, no email address, no tracking. Your locations are stored with your Apple ID, not ours.
How it works
Search for any address, city, or ZIP code. Give it a label — "Mom's house", "College", "The cabin" — whatever makes sense to you.
WeatherAlarm polls the National Weather Service and NOAA's Storm Prediction Center every few minutes, checking your locations against active alerts and outlooks.
The moment severe weather is issued for one of your locations, you receive a push notification telling you exactly what it is, where, and how serious.
Open the app to see all active alerts across all your locations at a glance, with severity levels, expiration times, and full details.
Data Sources
WeatherAlarm uses the same authoritative sources that professional meteorologists and emergency managers rely on — no third-party data brokers.
