Southern Californians are bracing for a second day of rain as a strong Pacific storm drenches the region.
Forecasters said to prepare for a total of three days of precipitation with showers arriving Monday and continuing until Wednesday morning.
The storm is expected to bring 1 to 3 inches of rain to the coast and valley areas, with the heaviest showers arriving Tuesday.
Mountain locations are expected to see from 2 to 5 inches of rain through Wednesday.
There is a chance of thunderstorms, especially Tuesday, which could bring possible flooding.
Concern is growing for residents in the Monrovia area near where the 2020 Bobcat Fire burned. Heavy showers could cause mud and debris flows in burn scar areas.
A flood watch is in place from Monday night through Tuesday night for portions of the Los Angeles County mountains, Antelope Valley, Santa Clarita Valley and San Gabriel Valley, including the cities of Lancaster, Castaic Lake, Palmdale, Pomona, Valencia, Santa Clarita, El Monte, Acton, East Los Angeles, San Gabriel, Pasadena, Newhall and Mount Wilson, according to the weather service.
A flash flood watch was issued for the Bond and Silverado burn scar areas Monday night through Tuesday evening.
A voluntary evacuation warning will be issued at 4 a.m. Tuesday for Silverado Canyon, Williams Canyon and Modjeska in the Bond Fire burn area in anticipation of possible debris flow along or near the burn scar, Orange County officials said Monday afternoon.
The flash flood watch includes the Santa Ana mountains and foothills, and some Orange County inland areas.
Snow is expected to remain around 7,000 feet Monday night, but may drop to 4,000 feet Tuesday night.
Forecasters are calling for 6 inches to a foot of snow above the 6,000 foot mark with up to 20 inches possible in some areas. Between 2 and 6 inches of snow is expected above the 4,500 foot level.
Drivers were reminded to carry chains when traveling in the mountains.
Dry weather is expected to return later in the day Wednesday and continue through the weekend.
