California Statewide Fire Summary

Wednesday, July 19, 2017

Approximately 6,000 firefighters are battling 17 large wildfires in California. In the northern region, a trough extending south into the Northern Operational region from a significant low in the Eastern Gulf of Alaska will be in until today. This arrangement will continue to produce a dry southwest flow aloft over the region and bring temperatures down to within a few degrees of seasonal norms. The marine layer has deepened a little and moved farther inland overnight. Above the marine layer the air mass will still be very dry, and this is particularly noticeable in the Bay Area. The presence of the trough will continue the gusty afternoon southwest winds and low relative humidity east of the Cascade-Sierra crest through today. Peak wind gusts will be from 25-38 mph and minimum relative humidity’s at 8-14%. In the southern region, high pressure will build a bit closer to the region today which will generate a moist, southeasterly flow over portions of the district. Monsoonal moisture will result in scattered wet thunderstorms over Southern California today south and east of a Ventura – Antelope Valley – Mojave National Preserve line. No storms are expected in the Sierras this week. Temperatures will be slightly warmer over the next two days with highs in the 90s in the valleys and lower foothills to 110 in the deserts. Temperatures will cool off a few degrees Thursday, but warmer weather may return this coming weekend. Winds of 10-20 mph will be possible Thursday afternoon along the Central Coast and the Kern County Mountains, otherwise winds will be light over most areas through the forecast period. Highs will be back into the upper 90s in the valleys to 100-105 in the San Joaquin Valley by Saturday and Sunday.


Does your family have a wildfire action plan? Before wildfire strikes, it is important that you get Set. Prepare yourself and your home for the possibility of having to evacuate. Create an evacuation plan that includes: A designated emergency meeting location outside the fire or hazard area with several different escape routes from your home and community. Also, don’t forget to make a plan for your pets. Lastly, designate an out-of-area friend or relative as a point of contact to act as a single source of communication among family members in case of separation. Visit:
