Residents of San Diego County are facing evacuation orders Tuesday as the Lilac Fire and Pala Fire have broken out in the region, officials say.

As wildfires continued to burn in Los Angeles, three fires broke out in San Diego County, prompting evacuation orders and warnings.

Nearly 100,000 San Diegans could loose power during the next round of power shutoffs after the National Weather Service issued another Red Flag Warning for the region for Monday and Tuesday as Santa Ana winds return.

Two new fires ignited in San Diego County on Tuesday, as firefighters continue fighting blazes further north in Los Angeles.

The National Weather Service's Los Angeles page screams “Particularly Dangerous Situation (PDS)” in hot pink letters against a gray background in a rare warning aimed at seizing attention ahead of extreme wildfire risk that's predicted to start in Southern California at 4 a.

San Diego County remains under the grip of another round of moderate to strong Santa Ana winds, paired with extremely dry air, elevating critical fire weather concerns.

"If fire ignition occurs, conditions are favorable for very rapid fire spread and extreme fire behavior," the NWS warns.

For the first time in a long while, a cold storm is expected to arrive this weekend, bringing showers and low snow levels.

A red flag warning due to wildfire danger will be in effect from 10 a.m. Monday to at least 10 p.m. Tuesday for inland valleys and mountain areas throughout the county, according to the National Weather Service.

This weekend's cool temperatures and higher humidity are expected to give way to more Santa Anas and a new red flag warning Monday.

The National Weather Service expects lows of 45 degrees on Tuesday, Wednesday and Thursday nights in San Diego. The Housing Commission and service providers decide whether to activate the inclement weather program each morning.
