• Even SoCal expected to see some rain
• “The greatest risk for areas of flooding will be along the western slopes of the mountains in northern and central California”
Stormy weather will resume in California with rain, mountain snow and even thunderstorms sweeping through early this week, according to the private forecasting company AccuWeather Inc.
After spotty rain dampened northern California over the weekend, a cold front moving onshore from the Pacific will end the stretch of dry weather that spanned the last two weeks across more of the state Monday into Tuesday.
“After a recent break from the active weather pattern, Californians must brace for the next brush with the atmospheric river of moisture aimed farther to the north,” says AccuWeather Meteorologist Kyle Elliott.
Residents across northern areas and the central coast will have to don their rain jackets for the first day of spring as rain increases on Monday.
“The worst of the storm will hold off until Monday night and into Tuesday, when the heaviest downpours are forecast to move onshore,” Mr. Elliott says.
Any heavier downpours could result in localized flooding, particularly in low-lying and poor-drainage areas. Drivers should take caution to avoid flooded areas.
"The greatest risk for areas of flooding will be along the western slopes of the mountains in northern and central California, where a total of 1-3 inches of rain can pour down," says AccuWeather Senior Meteorologist Kristina Pydynowski.
“Streams and rivers already running above-normal levels can exceed flood stage and pose a risk to homeowners living in flood plains," Mr. Elliott says.
"In addition to showers on Tuesday, gusty winds will blow and even thunderstorms will rumble," adds Ms. Pydynowski. "A few of the thunderstorms will produce small hail."
As the rain pours down in the lower elevations, burying snowfall will return to the Sierra.
"Snow levels in the Sierra will start above 8,000 feet on Monday, but will fall to 6,500 feet by late Tuesday," says Ms. Pydynowski. "A total of 1-2 feet of snow can further bury locations above 8,000 feet."
Travel will become treacherous through I-80’s Donner Pass, where a total of 3-6 inches is expected with blowing and drifting snow.
Impacts from the early week storm will not be confined to central and northern California, AccuWeather says.
"Showers will sweep down to Southern California on Tuesday, threatening to cause slick roads around Los Angeles," says Ms. Pydynowski. "Any showers should hold off until the late afternoon hours in San Diego."
Another storm quickly on the heels of the early week system may deliver steadier rain and more travel disruptions to Southern California at midweek.
"There can also be another round of thunderstorms in central California as more snow falls in the Sierra," Ms. Pydynowski says.
