Where do I find evacuation orders for the Mp18 Fire?
From the county sheriff and local emergency management, not from this site. Check the official California sources on our California page and your county’s alert system. FireRiskHere is for awareness only.
How current is this page?
The numbers come from the National Interagency Fire Center's WFIGS incident feed and the WFIGS perimeter service, refreshed every 15 minutes, plus NASA FIRMS satellite detections hourly. This page was last updated Oct 1, 2026, 01:01 UTC. Acreage and containment are what the incident team reports and can lag by hours.
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 →
