Rainfall, heavy at times, continued Sunday in Southern California and will remain at least through Monday in parts of the region.
“Drier weather is expected Tuesday night through late in the week, with cold nights for many areas Wednesday night through Friday,” National Weather Service forecasters said.
In the Inland Empire, rain is expected to continue in some locations Monday. At March Air Reserve Base near Riverside and Moreno Valley, there’s a slight chance of showers Monday with partly sunny weather otherwise and a high expected of 59 degrees. Showers are likely Monday morning in Murrieta, where the high was expected to reach 61 degrees.
There will be a slimmer chance for showers across the Inland Empire on Tuesday. In San Bernardino and Riverside, sunny skies are expected as early as Wednesday.
In Los Angeles, partly sunny weather was forecast for the Van Nuys Airport area on Monday, with a high near 63. There’s a chance of rain there Tuesday with sunny weather forecast Wednesday and Thursday.
In Long Beach, similar partly sunny weather was forecast for Monday with a high near 62. A slight chance of rain was forecast there Tuesday with sunny weather expected Wednesday and Thursday.
In Orange County, forecasters predict highs of 63 in Anaheim and Newport Beach on Monday and lows of 51 and 53 degrees, respectively. There’s a slight chance of showers before 10 a.m. in Anaheim with the rest of the day expected to be partly sunny, and in Newport Beach, forecasters expect partly sunny conditions during the day with a chance of rain overnight.
An off-shore low pressure system will bring a 15% to 20% chance of up to a tenth of an inch of rain, mainly in the afternoon, on Tuesday across Orange County.
On Wednesday, conditions will be dry. Temperatures are expected to be in the mid-60s on Tuesday and Wednesday for most of Orange County outside of the mountain areas.
Also in Orange County, the Orange County Fire Authority said crews on Sunday afternoon rescued a man clinging to a section of a culvert in cold, fast-moving water in a storm channel at Bolsa Avenue and Goldenwest Street in Westminster.

In addition, a L.A. County Department of Public Health advisory warning beach users “to avoid all water contact, especially near discharging storm drains, creeks, and rivers due to potentially higher bacteria levels in these areas,” will be in effect until at least 4 p.m. Monday. “This includes any runoff that may flow onto or pond on the beach sand.”
Inner Cabrillo Beach in San Pedro will remain closed until further notice following a Christmas Day sewage flow.
Hilda Solis, chair of the L.A. County Board of Supervisors, said county departments were “actively monitoring conditions and stand ready to respond to emergencies as needed.”
Caltrans has issued an indefinite closure for the 3.6-mile stretch of Topanga Canyon Boulevard known to experience mudslides between Pacific Coast Highway and Grand View Drive, in the unincorporated Topanga area. The reopening of the roadway was “dependent on improved weather and road conditions,” the agency said.
The Palisades Fire recovery work zone on PCH from Sunset Boulevard to Carbon Beach Terrace will remain open, “with crews on standby to respond to any storm impacts,” Caltrans said.
State Route 2 was closed from 3.3 miles east of Newcomb’s Ranch in La Canada Flintridge to state Route 138 in the Angeles National Forest.

Motorists were also advised to stay off the roads if possible and to exercise extreme caution if they do drive.
State and local officials have precautions in place for weather-related emergency response needs. Gov. Gavin Newsom has directed the California Governor’s Office of Emergency Services to pre-position fire and rescue personnel and resources in areas most at risk for flooding, mud, and debris flows — including parts of Southern California, with a particular eye toward burn scar areas.
