Greensburg, Pennsylvania

Watch the cases. Watch the sky.

Two instruments

One desk. Two kinds of weather.

Epidemiological weather and atmospheric weather both move on a clock you do not set. Casewatch maps confirmed cases. Stormlayer puts radar under your route. Both are live.

Stormlayer

Radar, satellite, severe polygons, and storm-avoiding routes. Start GPS when you need the map to follow.

Free to look. Pay for the desk.

The atlas and the radar stay public. Pro and Newsroom are the tools for a watchlist, a briefing, or a drive. Cancel anytime from the link in your Stripe receipt.
