It is going to be a wet Christmas.
The first of three storms that will drop just less than a foot of rain throughout the Bay Area is expected to hit The City on Friday night.
According to the National Weather Service, as many as 3 inches might fall in San Francisco by Sunday evening.
Soggy commuters can expect a one-day break in the wet weather Monday before the second round of more-powerful storms hits the area Tuesday.
Weather service meteorologist Will Pi said as many as 4 inches might fall in San Francisco, with the second system coming directly from the west.
The third storm will bring another 2 or 3 inches, arriving by Christmas Day.
Pi said this round of storms will drop the most precipitation this season. Though previous storms drenched the Bay Area in October and November, they were not as powerful as these storms and winds are expected to be.
"We could see them reach 40 mph," he said. "Tuesday will be the strongest winds."
Also different than previous systems, Pi said, is that temperatures will not drop to colder levels.
San Francisco will remain near the mid-50s all week. Temperatures will reach as high as 59 degrees Saturday.
The storm is typical of the La Niña weather pattern the California coast is experiencing, according to Pi. Typically, La Niña brings wet weather early, but tends to dry out come January.
Though San Franciscans may not enjoy the wet weather in the Bay Area, snow enthusiasts can look forward to the several feet expected to fall this weekend in the Sierra Nevada and around Lake Tahoe.
Nearly 8 feet of snow is expected to drop at elevations above 7,000 feet by Saturday night, according to the weather service.
Regardless of the final destination this weekend, driving will be treacherous throughout Northern California, Pi said.
"It’s going to be bad," he said.
