SAN FRANCISCO (CBS SF) – A fierce winter storm battered the Bay Area early Tuesday, flooding roadways, toppling trees, triggering mudslides, forcing school closures and stranding several drivers on water-logged Highway 121 in Sonoma County.
The storm – the second of three predicted for this week – roared into the Bay Area Monday night with driving downpours and gusty winds.
Flash flood warnings were issued for rivers and creeks in Alameda, Napa, Marin and Santa Cruz counties while flood waters rushed through downtown San Anselmo.

In Kentfield, where 6.30 inches of rain has fallen in the last 24 hours, fire crews helped residents stranded by the rising flood waters as a creek overflowed near College of Marin. At least seven people were rescued who were trapped in homes or cars.
Marin County Fire Battalion Chief Bret McTigue said about 40 homes in the area have substantial amounts of water in them.
Several Marin County school districts were forced to close including the Kentfield School District, the Ross School District, Tam Union, Mill Valley and Sausalito/Marin City schools. The Lagunitas and Fairfield-Suisun schools were also closed.

In San Rafael, a massive wall of mud crushed a home on Mountain View Ave. Fortunately, the family was able to escape unharmed.
Another massive slide — this one in the Santa Cruz Mountains — forced the CHP to shut down Highway in both directions.
The slide happened at West Vine Hill Road in Scotts Valley. CHP had no projected time of reopening the often troubled stretch of highway.
Mother Nature also put on a spectacular show at the Conn Creek Dam at Lake Hennessey in the Vaca Mountains where the spillway gave way to a raging waterfall.
Gusty winds toppled a big rig on the Richmond-San Rafael Bridge, shutting down all traffic in the eastbound direction for several hours.
In Pleasant Hill, a swollen creek helped a sinkhole opened up in Brookside Park.
In Redwood City, high tides and storm runoff flooded a mobile home park at 3015 E. Bayshore.
The North Bay, particularly Napa and Sonoma counties, bore the brunt of the wintry onslaught.
More than 2 inches of rain had fallen before daybreak in Yountville with the National Weather Service issuing a flood warning for the Napa River near St. Helena. The river ran over its banks at 5 a.m. with it expected to rise almost another 3 feet during the morning hours.
Downriver, the waterway was expected to crest above flood stage at 25.9 feet by 3 p.m. in downtown Napa.
Around Napa County, the storm was causing widespread damage and flooding. Lodi Lane in St. Helena was closed due to flooding as was Deer Park Road between Highway 29 and Silverado Trail.
Flooding was widespread along the Silverado Trial as Yountville Cross Road and Oak Knoll Ave were also closed by flooding.
A mudslide closed Redwood Road about 1/2 mile from the Napa city limits and another slide forced the closure of Redwood Road at Browns Valley Road.

Runoff from the downpours rapidly filled the San Lorenzo River forcing homes to be evacuated in Felton Grove area.
Meanwhile, runoff from the storm filled Walnut Creek and turned the normal placid waters into a raging river.
In San Francisco, high tides and storm runoff flooded the heavily travel Embarcadero, reducing it to one lane in the northbound direction. Across the Bay in Oakland, a 100-foot eucaltptus tree toppled onto Shepherd Canyon Road closing the roadway.
