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.

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.

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.

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.

Dry air and gusty winds will continue throughout San Diego County through the middle of next week, followed by cooler and cloudier weather by the end of the week and possible light precipitation by next weekend.

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

The National Weather Service on Wednesday extended the wildfire warning through the end of the week for much of East County.

There may be some potential respite from the low humidity with some light rain west of the mountains next weekend, but then the region will return to dry, clear weather, forecasters said.

Forecasters say the moisture will do virtually nothing to tamp down the threat of wildfires in a region starving for rain.

Forecasters in Southern California expect to issue a red flag fire weather warning starting Monday, with the 'risk of large fire growth' should ignitions occur.
