About this data

Not an official warning service. Warnings and watches are drawn from the National Weather Service, and discussions, outlooks and reports from its Storm Prediction Center (Data: NOAA/NWS, NOAA/SPC). When a warning is issued for you, act on it — and use weather.gov or a NOAA Weather Radio for where you are.

Radar: NOAA MRMS mosaic via nowCOAST, drawn live with no last-good copy: an empty radar means we cannot see, not that the sky is clear. Warnings and watches: NOAA/NWS. Discussions, outlook and reports: NOAA/SPC. The maps are ours; the warnings are theirs.
