LOS ANGELES (KNX) — Red Flag warnings were issued across Los Angeles and Ventura Counties Thursday, due to gusty northeast winds and “very low” relative humidity, according to the National Weather Service.
Santa Ana winds between 30 to 50 mph will continue Thursday night, then decrease further to 20 to 40 mph on Friday, before decreasing to 15 to 30 mph by Saturday and Sunday.
Meanwhile, very low humidities will change little through Saturday, with daily minimums of two to 10% common and poor overnight recoveries especially in the valleys and mountains, according to the National Weather Service.
Red Flag Warnings will remain in effect through 6 p.m. on Friday, NWS said, adding that there is a 50% chance that the coastal areas, San Fernando and San Gabriel Valleys will not reach Red Flag criteria past 6 a.m. Friday.
“There is also a 30% chance that the Ventura Valleys, Santa Clarita Valley, and interior mountains will need to be extended into Saturday or Sunday,” NWS said.
