WxAlerts watches continuously and tells you when something concerns a place you care about: National Weather Service alerts, GOES-19 lightning, storm cells tracked while they are still cells, SPC outlooks and observations. Nothing safety-related is behind a paywall, and nothing here is an official government source. Always follow your local officials.
Pick how you want to be told
There are three ways in, and most people end up using more than one.
| Route | Best for | Setup time |
|---|---|---|
| The live map | Checking on a storm right now | None |
| The apps | Push notifications on a phone or desktop | A minute |
| Home Assistant | Automations, dashboards, lights and speakers | Ten minutes |
Where to go
- I want a warning on my phone. Follow Get your first alert on your phone. On an iPhone without the app, see Alerts on iPhone without the app.
- I want to watch more than one address, or tell other people. See Saved places and alert rules.
- I want my house to react. The Home Assistant integration turns NWS alerts and storm cells for your places into entities you can automate against. It is part of the Supporter plan.
- I want to build on the data. Start with the developer docs. The alert and lightning feeds are both public.
- I am a storm spotter. See Spotter reports.
- I run a weather station. See Weather stations.
- I want to read the storms on the map. See Storm analysis.
Every warning is taken from three independent National Weather Service feeds at once and pushed straight out. How an alert reaches you walks the whole path.
Something wrong?
Bad polygons and missed alerts are the most useful bug reports the project gets. Bring them to Discord, or open an issue on the repo.
