Active Fire Perimeters (CalOES Tracked)

Feature layer showing the active fire perimeters 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.
