This month has been much quieter in terms of wildfires in Southern California after heavy rains occurred earlier this January. The region has been able to dry out, and portions are currently experiencing abnormally dry conditions or a moderate drought. A Santa Ana wind event has set up this weekend as high pressure sits over the interior West. Therefore, strong, offshore winds will occur through Monday. Winds may gust as much as 70 mph in the San Gabriel Mountains while the Los Angeles Basin experience wind gusts up to 30-35 mph. That combination with hot, very dry conditions will make the Southern California prime for wildfires. Relative humidity values will mainly be between 10 and 30%, which indicates a dry airmass.
On Saturday, the Storm Prediction Center has placed portions of Southern California in a ‘Critical’ risk for wildfires. Temperatures will mainly be in the 70’s.
Then on Sunday, the worst conditions will likely occur. Relative humidity values will be at their lowest while temperatures soar into the mid to upper 80’s in the L.A. Basin. This is definitely a concerning forecast for wildfires.
Similar conditions will persist into Monday. Temperatures may top off at 90 degrees in and around Los Angeles while the winds continue to blow strong.
