Three storm systems forecast for Thursday through Monday could drop up to 8 inches of rain in the North Bay mountains and lesser amounts across the rest of the Bay Area, National Weather Service forecasters said.
High winds of 15 to 25 mph with gusts up to 35 mph are also forecast, which will make driving difficult, especially for taller vehicles. The wind may cause fallen trees and power outages, according to the weather service.
On the Midpeninsula, winds of 8 to 17 mph, with gusts as high as 23 mph, are forecast for Friday.
It's "going to be a little on the breezy side," weather service forecaster Diana Henderson said.
The rain will mean slick roads and longer commute times.
Weather service officials said the rain will start falling Thursday and continue into Friday, with a lull late Friday and Saturday morning. On Saturday afternoon, the rain is forecast to start again and persist through Monday.
Rain totals in the valleys and urban areas will be less than in the mountains. Forecasters are predicting 3.05 inches for San Francisco over the five-day period, 1.72 inches for San Jose and 6.72 inches for Santa Rosa, according to the weather service.
Creeks and streams are expected to rise as the ground is saturated from recent storms, according to meteorologist Holly Osborne with the weather service's California Nevada River Forecast Center.
No other major rivers in the Bay Area are forecast to possibly reach flood stage during the five-day period, Osborne said.
