What the sources tell you
This page combines agency incident reporting with separate satellite and map layers. They can update at different times and answer different questions.
WFIGS / NIFC
Use this for the reported fire name, acreage, containment, incident location and agency update time shown on this page.
NASA FIRMS
Heat detections can show recent thermal activity, but they are not an official acreage or containment figure and are not automatically attributed to this incident.
Agency perimeter layer
When a perimeter is available in the map layers, it may have a different timestamp from the incident report. The fire pin itself is only a reported location.

How this fire has changed
WildfireSignal keeps a short history of the agency values it has observed so you can see how reported acreage and containment have changed over time.
Across WildfireSignal\'s saved agency reports from Sep 20 to Sep 30, reported containment increased from 5.0% to 100%.
These are differences between agency reports saved at different times, not a measured spread rate. Acreage can decrease after mapping corrections, and unchanged figures do not prove conditions are unchanged.

Questions about CHILENO Wildfire
Where is CHILENO Wildfire?
The official incident record places it in PETALUMA, Marin, California. The map pin is a reported location, not the full fire boundary.
How large is CHILENO Wildfire?
The latest available record reports 341 acres (approximately 138 hectares). This is reported incident size, not a measurement of current flames, and agencies can revise it.
How contained is CHILENO Wildfire?
The latest available record reports 100% containment. Containment describes control work intended to stop spread. It is not the percentage extinguished or an all-clear for nearby communities.
When was CHILENO Wildfire discovered?
The reported discovery date is Sep 20, 2026, 7:40 PM ET. Discovery time may differ from ignition time; elapsed time does not establish continuous burning.
Where should I check evacuation orders and road closures?
Use local emergency management, the sheriff or other law enforcement, and official fire-agency updates. WildfireSignal does not verify evacuation zones, open roads, or safe travel routes. The official-information section provides starting points; it does not establish that orders are present or absent.
Why can the map and the incident report differ?
Agency records, mapped perimeters and NASA satellite detections are updated on different schedules. Satellite heat near a fire is not automatically attributed to that incident. Older or unavailable data does not establish that an area is safe.
