Most of Los Angeles County has been facing heat and a red flag warning, but it was set to expire in most of the county Thursday night — and temperatures are set to drop around 20 degrees by Sunday, the National Weather Service's Stuart Seto told KPCC.
"This will probably be one of the last red flag warnings for about a week, because what we're going to see this Sunday is a low-pressure area coming at us that might bring a slight chance of precipitation — about 20 percent," Seto said.
Temperatures are predicted to drop from 95 degrees in downtown L.A. on Thursday to 75 on Sunday. After Sunday night, the rest of next week will deliver below average temperatures for this time of year — in the mid-70s, according to Seto.
Several temperature records were tied on Thursday. At the L.A. International Airport, a previous record of 95 degrees set in 1999 was tied. At the National Weather Service office in Oxnard, 96 degrees Thursday tied a record set all the way back in 1942. And in Camarillo, 96 degrees there ties a record going back to 1965.
Earlier Thursday, L.A. County was seeing winds of 15 to 25 miles per hour, with gusts of around 40 miles per hour and some isolated gusts up to 50 miles per hour. There was also low humidity, coming in at around 10 percent in several areas.
The mountains were seeing higher winds, up to around 40 to 43 miles per hour and averaging 25 miles per hour. In the San Fernando Valley, there were reports up to 30 miles per hour.
Seto warned that gusty cross-winds can be dangerous, especially for high-profile vehicles, motorcycles and lighter cars that can easily be blown around. Those can be a problem up in mountain passes.
There was a chance the red flag warning could be extended for the mountain areas into Friday, Seto said.
