Everything you need,
nothing you don't.

WeatherAlarm is focused on one job: making sure you know when severe weather is headed toward someone you care about.

📍

Multiple Locations

Monitor Mom, Dad, Grandma, and anyone else — each labeled with a name you choose, not just an address.

🌪️

NWS Watches & Warnings

Instant alerts for tornado warnings, severe thunderstorm warnings, winter storms, floods, and dozens of other NWS products.

SPC Convective Outlooks

Know when a location enters a Marginal, Slight, Enhanced, Moderate, or High risk area before storms even develop.

🔔

Push Notifications

Alerts arrive directly on your iPhone — no need to open the app or watch a radar. You'll know the moment something changes.

📱

Multi-Device Sync

Install on multiple iPhones and your saved locations automatically sync across all of them via iCloud.

🔒

Private by Design

No account sign-up, no email address, no tracking. Your locations are stored with your Apple ID, not ours.

How it works

Simple to set up.
Always watching.

1

Add a location

Search for any address, city, or ZIP code. Give it a label — "Mom's house", "College", "The cabin" — whatever makes sense to you.

2

We watch 24/7

WeatherAlarm polls the National Weather Service and NOAA's Storm Prediction Center every few minutes, checking your locations against active alerts and outlooks.

3

You get notified instantly

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.

4

Review and take action

Open the app to see all active alerts across all your locations at a glance, with severity levels, expiration times, and full details.

Powered by official
government data.

WeatherAlarm uses the same authoritative sources that professional meteorologists and emergency managers rely on — no third-party data brokers.
