The downpour is expected to begin Monday evening in the North Bay and move south overnight. Precipitation is expected to ease by Tuesday afternoon after soaking the coastal mountains of Sonoma and Santa Cruz with up to 5 inches of rain. According to the US National Weather Service, low-lying areas of San Jose, San Francisco, and the East Bay could receive 1 to 2 inches of rain. The Bureau of Meteorology is alert to localized flooding and road closures, especially during Tuesday morning’s commute.
Another big attraction of this powerful storm is howling winds.
“We expect gusty winds, especially in coastal and coastal areas,” he said.
After the first storm, the Bay Area will remain damp through New Year’s Eve, with “unstable” weather patterns bringing sporadic daily showers almost every day.
In an update Sunday morning, the Bureau of Meteorology noted an 18th-century Scottish melody often sung at the stroke of midnight, saying, “The model will wait for the next rain until most people stop singing Auld Lang Syne.” It suggests that there will be no break in the December 31.

A weather pattern often referred to as the “Pineapple Express” developed in the western Pacific near Guam. This means wet weather and winds will not bring sub-zero temperatures to the Bay Area, with highs in the high 50s and lows in the 40s.
The Bay Area saw a mild Christmas weekend, but much of the country emerged from a massive winter storm that saw freezing temperatures and whiteout conditions, killing at least 29 people across the United States. .
Californians were most affected by the Arctic blast, especially in Denver and Chicago, which disrupted air travel and caused flight delays across the country. In the Bay Area, three major airports have canceled hundreds of flights as travelers reschedule their vacations. Some were stuck at the airport for hours, while others chose to drive across state lines rather than spend Christmas alone at home.
Airport troubles continued on Christmas Day, with nearly 40% of flights delayed at San Jose Mineta International Airport and an average delay of more than 50 minutes at Oakland International Airport, according to Flight Aware.
But this week’s storms will bring much-needed rainfall to California’s drought and snow seekers on Lake Tahoe.
The upper Sierra Nevada mountains are expected to receive several snowfalls totaling about 3 feet over the next weekend. The first batch of powder falls to over 7,500 feet in elevation Monday night, and as the week gets progressively colder, snow levels drop to he 4,500 to 5,500 feet.
California’s snowpack, which supplies about one-third of the state’s drinking water, is already off to a healthy start after two storms that dropped several feet of snow in early December. All three of her Sierra regions are now reporting abundant snow cover, averaging 150% of normal for this time of year. But water experts warn that last year he was followed by a series of very dry months before a massive winter storm in December.
81% of California is currently experiencing severe drought, with parts of the San Joaquin Valley experiencing exceptional drought, the worst of the five categories.
A strong atmospheric river could be linked to an inbound storm passing through NorCal on Tuesday. More storms will follow, perhaps through weaker ones. We will have a Weather West update tomorrow morning. #CAwx https://t.co/mRbHBvGBIO

This week’s Atmospheric River brings a different kind of challenge. Along with the snow, skiers can see gusts of 65 to 85 miles per hour at the summit, and drivers heading to Lake Tahoe will also experience strong winds.
