About SeeStorm

Why this exists

Severe weather data keeps people safe. SeeStorm keeps it free, open, and easy to see. No ads, no paywalls, no account required. Born in Wisconsin during the April 2026 tornado outbreak, it now covers severe weather across the United States.

How it's built

Direct from the National Weather Service and the Iowa Environmental Mesonet radar service. Watches, warnings, and advisories render as they're issued, in the NWS-standard severity colors. Open-source; operated as a public service by eclecti-build.

Source

SeeStorm is open source under the MIT license. Code lives in two repositories: seestorm-client (this site) and seestorm-ingest (the NWS data poller). Issues, pull requests, and forks welcome.
