Another storm slammed the Southland Tuesday, with substantial rain and gusty winds expected to continue through Wednesday morning and raising fears of localized flooding.

“Rain will likely increase in coverage and intensity this evening, especially for Los Angeles County, in response to a strengthening jet aloft,” the National Weather Service’s Los Angeles office tweeted Tuesday. “Roadway flooding and rock/mudslides are possible with significant water flow through local rivers expected. Be careful out there!”

A flood watch was in effect for Orange County, including the Santa Ana Mountains, until 2 p.m. Wednesday. A flood advisory was in effect until 4:30 a.m. Wednesday for all parts of Los Angeles County except for the Antelope Valley, and until 1 a.m. Wednesday in Riverside and San Diego counties.

The mountains and foothills were receiving the highest rates of rain, possibly between a half-inch and 1 inch per hour Tuesday evening, forecasters said. Rainfall was expected to range from 1 inch to 2.5 inches across other parts of Los Angeles County on Tuesday evening, according to the weather service.

LAX set a record Tuesday for rainfall on that date with .61 of an inch, breaking the old record of .43 set in 1982

Snow levels remain high, in the 7,000- to 9,000-foot range, and no significant winter weather issues are anticipated, the NWS said. Winds were expected to gradually decrease overnight.

In Azusa, one person remained missing after 11 other people and six dogs were rescued from a swollen San Gabriel River on Monday.

In Beverly Hills, a sinkhole temporarily closed northbound Beverly Drive to Coldwater Canyon on Tuesday.

Late Tuesday, Caltrans announced that all lanes of Pacific Coast Highway were closed between Seapoint Street and Warner Avenue in Huntington Beach due to flooding.

Dry weather is expected to return Wednesday night through at least Friday, with a chance of light precipitation over the weekend.
