After two days of blustering winds and dangerously low humidity, a red flag warning of critical fire weather conditions expired for much of Los Angeles County Thursday, but the warning will remain in place in the mountains, Santa Clarita Valley and Angeles National Forest.
“Santa Ana winds continue will continue to diminish gradually (Thursday night) into Friday, with wind gusts generally ranging between 25 and 35 mph across the mountains of Los Angeles and Ventura counties, as well as the Santa Clarita Valley and Ventura County Valleys,” according to the National Weather Service. “Very dry air will persist through the rest of the week, with single digit minimums common and poor overnight recoveries.
“The red flag warnings have expired for some areas as of 6 p.m. this evening, and although weaker and more localized winds are expected (Thursday night) through Friday they should be just strong enough to keep critical conditions going through Friday in the windiest locations.”
The red flag warning will remain in effect until 6 p.m. Friday for the Los Angeles County Mountains, Angeles National Forest and Santa Clarita Valley.
In the mountains and national forest, winds are forecast between 15 and 25 mph, with gusts up to 35 mph, through Friday, coupled with humidity levels of 2 to 8%. Winds should be slightly lighter in the Santa Clarita Valley, generally ranging from 10 to 25 mph, although gusts to 35 mph are also possible in that area.
The red flag warning expired in the Santa Monica Mountains Recreational Area, the Los Angeles coastal area including downtown, and the San Fernando and San Gabriel valleys.
In Orange County, where the red flag warning was to be in effect through much of Thursday, but it was canceled Wednesday night thanks to dramatically weakened winds.
In the Antelope Valley, a hard-freeze warning will be in effect until 10 a.m. Friday amid sub-freezing morning temperatures of 18-25 degrees.
