The Southland will be pummeled by rain and snow again before the new year arrives.

Rain from the Santa Barbara area will develop into a heavier storm Wednesday night into Thursday.

The foothill and mountain areas could get around 5 inches of rain, and then 1 to 3 inches in lower-lying areas. Mountain areas above 5,000 feet could get 1 to 3 feet of snow.

The National Weather Service has issued a flash flood watch for Los Angeles County's recently burned areas. It takes effect at 6 p.m. Wednesday through Thursday, covering the scars near Lake Hughes, and the Bobcat, Dam, and Ranch 2 fire areas in the San Gabriel Mountains.

In addition, Orange County is under a flash flood watch until 4 p.m. Thursday, including the Bond Fire burn area. A voluntary evacuation warning around the burn scar for the Silverado, Williams, and Modjeska canyon areas is in effect until the flood watch ends.

Several of the areas are anticipating mudflow and debris that may close roads, such as parts of Glendale, Monrovia and Brentwood, according to the L.A. County Department of Public Works. Warning levels have increased to Phase 2 in some areas, meaning there's a risk for streets to become blocked by debris.

The department has also issued a winter storm warning for the Bobcat and Lake fire burn areas and is advising a few dozen households to prepare for possible evacuations. Area residents are also urged to put out sandbags and get trash cans off the streets.

CalTrans has cleared parts of the Angeles Crest Highway above La Cañada Flintridge. Snow chains are required because the storm is expected to bring heavy snow and possible closures. The NWS is also cautioning anyone doing mountain driving to practice extra caution and review safety tips.

While the storm is expected to pick up tonight in L.A. County, NWS meteorologist Mike Wofford says everything should clear up before New Year's Eve.

“It'll be chilly, expecting some lows down into the 30s there in the Valley for around New Year's, but we're not expecting any rain until at least the middle of next week,” he said.
