LOS ANGELES (CBSLA.com) — A red-flag warning remains in effect Tuesday for the mountain and valley areas of Los Angeles, Ventura and Orange counties, with forecasters saying strong winds and low humidity threaten to give rise to wildfires.

The warning is scheduled to remain in force until 4 p.m. in the San Gabriel and Santa Monica mountains and the Angeles National Forest in Los Angeles County, as well as Orange County, the mountains of Ventura County and the Los Padres National Forest.

Forecasters predicted that areas under warning would be swept by northeast winds blowing at sustained speeds of 15-25 mph and gusting at 40 mph while humidity levels remain at 3 percent to 8 percent.

But the warning was allowed to expire at 8 p.m. Monday in coastal areas of Los Angeles and Ventura counties.

Temperatures will be in the high 70s and low 80s in many Southern California communities.
