Gusty Santa Ana winds paired with low humidity and drought conditions across Southern California prompted the National Weather Service to warn of extreme fire danger in the region through the weekend.
The weather service warned of dangerous conditions on Friday, and red flag warnings were issued for Los Angeles, Ventura, Riverside, San Bernardino and Orange counties. The warning was expected to last until 6 p.m. Sunday.
"A red flag warning means that critical fire weather conditions are either occurring now, or will shortly," the service stated.
On Friday, the strongest recorded gusts were 51 mph in the Warm Springs area, 46 mph in Tonner Canyon, 42 mph at Camp Nine and 41 mph in Newhall Pass, according to the weather service.
Northeast winds between 15 and 30 mph, with gusts reaching 45 mph, were expected on Saturday, with the strongest winds predicted to blow around noon.
The winds would likely weaken Sunday afternoon, then turn onshore Monday, the weather service stated.
The lowest daytime humidity on Saturday was expected to be 10 to 15 percent, with “poor recovery” that night - mainly in windy locations. Sunday’s low humidity would likely be around 5 to 10 percent.
