The fire severity index shows how easily a wildfire would spread in England and Wales over the next five days. Satellite heat detections show possible fires. Report any wildfire on 999.
Wildfire risk in the UK
A heat detection is not a confirmed wildfire. Places with detections on 3 or more separate days (steelworks, refineries, flares) are left out, and so is a fire that burns in one place that long. Status follows the fire severity index forecast (how readily a fire would spread, not a fire burning), which covers England and Wales only.
