About this page
This page is generated automatically for every wildfire whose reported size reaches 1,000 acres, from FireRiskHere’s archive of the National Interagency Fire Center’s WFIGS incident feed (captured every 15 minutes), the WFIGS interagency perimeter service, and NASA FIRMS satellite detections. It stays online after the fire is contained as a record of the incident. Nothing here is an official notice — for evacuation orders and road closures follow your county sheriff and local emergency management. How the site works →
