Los Angeles County sent extra fire trucks to Malibu as Santa Ana winds of 70 miles per hour were forecast, and a Red Flag Warning posted for the mountains and canyons Wednesday.
National Weather Service forecasters said winds might peak at 70 miles per hour on mountaintops, and in the canyons, from the Hollywood Hills west through the Santa Monica Mountains.
The Santa Clarita Valley, including the tangle of freeways in the Newhall pass, was also predicted to see maximum wind gusts above 60 miles per hour, the NWS said.
Temperatures above 80 degrees were also in the cards, and the desert air being compressed through the mountains would drop the humidity to below 10 percent, forecasters said.
"Given this combination of strong offshore winds and low relative humidity, critical fire weather conditions are expected for most of Ventura and Los Angeles counties," the NWS said in a statement issued at 9 a.m.
In the morning, the NWS elevated the conditions from a fire watch to a full-fledged Red Flag Warning to take effect at 6 p.m., and at midafternoon forecasters advanced the Red Flag Warning start time to "now."
The warning remains in effect through 6 p.m. Monday.
