Weather conditions that are likely to rapidly spread fire — high winds, rising temperatures and low humidity — are forecast for Southern California for Sunday.
Those winds also could bring rain to the region starting Tuesday.
The National Weather Service has issued a red flag warning for the Riverside and San Bernardino valleys and mountains, the San Gorgonio Pass, Cleveland National Forest and eastern Orange County that will be in effect from 1 a.m. to 6 p.m. Sunday. Winds from the east at 20 to 30 mph with gusts to 50 mph are predicted along with humidity of 10% and a high temperature of 92 degrees. Humidity will remain low Monday, but the temperature will decrease a few degrees, and the wind speed will lessen, the NWS said.
A red flag warning means that critical fire weather conditions either exist or will shortly.
Although a red flag warning had not been declared for the Los Angeles area and eastern Ventura County as of noon Saturday, dangerous weather conditions will exist. High temperatures in the 80s to low 90s on Sunday could break records for Nov. 17 in downtown Los Angeles and at LAX and Long Beach Airport, the NWS said.
“Gusty winds, near-record high temperatures and dry conditions could bring critical fire weather conditions to the region on Sunday,” the weather service said.
High winds have fanned the flames of numerous fires in Southern California this fall, resulting in structures being destroyed and lives being lost. Fire officials urge residents to have an evacuation plan in place that includes food, water, a fully charged cell phone and easily accessible important documents and photos.

The officials also recommend being careful with activities that could cause a spark such as mowing a field or parking a car on brush.
Beginning on Tuesday, a chance of showers is forecast through Friday, along with a cooling trend that could pull the high temperatures down into the mid-60s.
I’m in SoCal this weekend and just went for a hike near Santiago Peak in the OC. I can feel the RH drop and feel a light shift in the wind. Mother nature is setting up for a traditional off shore wind event. Be prepared and visit @CAL_FIRE @NWS for updates #ReadyforWildfire https://t.co/gY9hU2vLUS
