Active Fires (CalOES Tracked)

Cal FIRE is the only authoritative fire data source for the State of California.  

All other sources are non-authoritative.


Feature layer showing the active fires being tracked by Cal OES GIS.

Fire information is taken from the National Fire and Aviation Management (FAMWEB) in the form of ICS-209 reports.  During normal operations these 209 reports are downloaded once a day at 0630, or soon after.  During a SOC activation these 209 reports will be downloaded twice a day at 0630 and 1800.  Cal OES GIS considers the FAMWEB ICS-209s as the authoritative fire information source.
Fire perimeter data is downloaded from the National Interagency Fire Center (NIFC). 

The data for map is updated daily, M-F, by 0800, the map text by 0900, when there are active fires being tracked by Cal OES.
If the SOC is activated the fire map will be updated daily, Sun-Sat, by 0800, the map text by 0900, until the SOC stands down.
For a fire to be tracked by Cal OES GIS it needs to be: >100 acres in size Have an ICS-209 form.
CalOES GIS indicates a fire as contained when it has reached >=90% containment.
