A red flag warning remained in effect Tuesday for parts of Southern California as gusty winds contributed to ongoing "critical fire weather conditions."

Northeast winds of up to 40 mph are expected to buffet mountainous areas of Los Angeles and Ventura counties, as well as the Santa Clarita and San Fernando valleys, according to the National Weather Service.

The weather forecast also called for single-digit relative humidity, which has also prompted concerns over increased fire danger, the Weather Service said.

The red flag warning is scheduled to expire at 4 p.m.

Officials advised motorists and residents that strong crosswinds may have an impact on high-profile vehicles, while possibly toppling tree limbs and causing localized power outages.

Meanwhile, a hard freeze is likely Tuesday morning in the Antelope Valley, where temperatures may dip to as low as 28 degrees, according to the NWS.

However, low temps do not decrease the possibility of fire, officials said.

"Temperature doesn't have an effect on the fire — it's the relative humidity and then the wind," said San Bernardino County Fire Marshal Mike Horton. "The wind speeds and that low RH are what cause wind-driven fires and very brittle, dry fuels."

Property owners should not initiate any controlled burns or weed burning while red-flag warnings are in effect, Horton said. He advised residents to check with their local fire department for information on conditions in their respective areas.
