A red flag warning was issued for most of Los Angeles and Ventura counties, and it was set to go into effect at 3 a.m. Thursday and go on until 6 p.m. Friday.

The National Weather Service warned of Santa Ana winds blowing northeast to east with gusts about 35 to 60 mph in the  inland regions of Orange County, the Coachella Valley and communities in the mountains and inland valleys.

In L.A. and Ventura counties, gusts could reach 70 mph in the mountains and 55 mph on the coast and in the valleys. Forecasters expect peak winds on Thursday between 10 a.m. and 8 p.m.

Humidity could drop to 5 to 10%, according to the National Weather Service.

"The gusty NE winds along with warm and very dry conditions will lead to a potential for critical fire danger and rapid fire growth," the agency said.

Mike Des Forges with Ventura County Fire Department said the agency would be beefing up staffing with additional engines to prepare for the potentially rapidly shifting conditions.

“The Santa Ana Winds are, in effect, a blowtorch,” he said. “They cause extreme, extreme fire behavior.”

Early Monday, SoCal Edison's power shutoff watch only included 12,000 customers, mostly in Mono and Kern counties. The company in late September cut service for dozens of homes in the unincorporated areas between Beaumont and Banning in Riverside County for nearly six hours.

Meanwhile, Pacific Gas & Electric issued a wider warning in Northern and Central California this week, where millions of people across 34 counties could be affected by shutoffs starting at midnight.

PG&E power lines ignited some of the most devastating fires in California over the past two years. In May, state regulators approved a rule that allows utility companies to preemptively turn off service to avoid blazes.
