The latest in a series of powerful Southern California winter storms brought more rain and potential for destructive flooding and mountain snow Monday to the already saturated San Diego area.
The storm, which moved into the county on Sunday, delivered widespread heavy showers, though the local downpours — and resulting mudslides and runoff-submerged roadways — were not as serious as those in Orange and Los Angeles counties, according to the National Weather Service.
More rain is on the way Tuesday, though the intensity will decrease.
“More widespread precipitation this morning will become more showery and continue at times through Friday and possibly into Saturday,” the weather service said. “Areas of flooding are possible into this morning with the flood threat becoming more localized during today.”
The region could get another 1 to 1.5 inches near the coast to 2.5 to 3.5 inches inland over the next several days.
Due to the predicted severity of the storm, Gov. Gavin Newsom declared a state of emergency in eight counties, including the San Diego region, over the weekend. The proclamation includes provisions authorizing a California National Guard response if needed, facilitating unemployment benefits for impacted residents and making it easier for out-of-state contractors and utilities to repair storm damage.
The other counties included were Los Angeles, Orange, Riverside, San Bernardino, San Luis Obispo, Santa Barbara and Ventura.
Over a two-day period ending late Monday afternoon, the dark bands of clouds had dropped anywhere from a hundredth of an inch to more than 3 1/2 inches across the coastal, inland-valley and mountain communities of San Diego County, the weather service reported.
Among the 48-hour precipitation tallies as of 4:15 p.m. were 3.56 inches in San Onofre; 2.49 at Palomar Observatory; 2.02 in Oceanside; 1.99 in Fallbrook; 1.56 at Rainbow Camp; 1.53 in Bonsall; 1.42 in Carlsbad; 1.23 in Vista; 0.96 in Encinitas; 0.88 in Deer Springs; 0.79 in San Marcos and Valley Center; 0.66 in Escondido and at Lake Wohlford; and 0.3 in National City.
Other rainfall totals included 0.22 in Rancho Bernardo; 0.2 at Miramar Lake; 0.17 in Flinn Springs and Point Loma; 0.13 in Mission Valley; 0.12 in Granite Hills and Kearny Mesa; 0.1 in Poway and Santee; 0.08 at Ramona Airport and San Diego International Airport; and 0.02 in Chula Vista. No precipitation was recorded in the local deserts over the period, according to the NWS.
The showers led to scattered San Diego-area road closures Monday morning, according to the California Highway Patrol, including on state Route 78 at Cloverdale Road in the San Pasqual area, due to a sinkhole; SR-78 at Emerald Drive in Vista, and the El Camino Real entrance to eastbound SR-78 in Oceanside, both for flooding; and in the 5400 block of Olive Hill Road in Bonsall, where a tree fell across traffic lanes.
San Diego Gas & Electric has increased the number of field crews and equipment available “to restore power as quickly and safely as possible should power outages occur,” a statement from the utility company read.
Call 9-1-1 and SDG&E at (800) 411-7343 to report downed power lines.
An NWS flood watch will be in effect until 10 a.m. Wednesday for the city of San Diego as well as the communities of Borrego Springs, Carlsbad, Chula Vista, El Cajon, Encinitas, Escondido, Julian, La Mesa, National City, Oceanside, Pine Valley, Poway, San Marcos, Santee and Vista. Excessive runoff could result in flooding of rivers, creeks, streams and other low-lying locations, meteorologists advised.
Forecasters also warned of the likelihood that strong winds — from 15 to 25 mph and gusts up to 35 mph in some places — could blow away unsecured outdoor objects, snap off tree limbs and cause power outages.
Additionally, a high-surf advisory was slated to be in effect until 10 p.m. Monday, with ocean breakers from 6 to 8 feet high and sets up to 10 feet, along with a small-craft advisory from San Mateo Point to the Mexican border.
South to southeast winds will increase in intensity over the day Monday, with gusts from 25 to 30 knots, the weather service advised. The high- surf conditions are expected to decrease overnight and Tuesday.

The county advised against putting debris near curbs during rainy weather, where it can wash away and cause a hazard.
This week’s storm comes after a spate of historically heavy downpours that left roadways, commercial districts and residential neighborhoods underwater across the region two weeks ago. The wettest day, Jan. 22, delivered the highest 24-hour rainfall amounts in San Diego since 1850, according to the NWS.
The inundation, which washed away many a parked car and heavily damaged or destroyed hundreds of homes, prompted the city and county of San Diego, along with Newsom, to declare states of emergency.
Since then, authorities have been taking steps, including monitoring tens of thousands of storm drains, to prevent more storm-driven destruction, Gloria said during a recent news briefing. He urged those who live or work in flood-prone areas to remain proactively vigilant as well.
“Now is not the time to remove your sandbags,” the mayor said. “We can’t predict Mother Nature. She’s unpredictable.”
The city and the San Diego Housing Commission have opened a new 50-room shelter at a former hotel site in the Midway district to provide a refuge from those impact the recent storms.
“Providing shelter and support for our neighbors whose lives were upended by the storm is a top priority,” City Council President Sean Elo-Rivera said. “These creative options were possible through collaboration between the city, county, the Housing Commission and state of California. The road ahead of us is long, but this quick and meaningful action shows that we can create creative housing solutions when we all work together.”
The county’s Assessor’s Office, Public Health, Behavioral Health, Public Works and Department of Environmental Health and Quality will be at the City Assistance Center to provide services to those impacted by the storms.
