Although Pleasanton and the Tri-Valley are expected to be sunny during the weekend, the San Francisco Department of Public Works is advising residents to prepare for the upcoming storm season, as forecasters project high winds and rain beginning Monday and extending through Tuesday.
The National Weather Service is forecasting a "potent storm system" will move into Northern California beginning late Monday and continuing through Wednesday morning. The system originates from a major typhoon that hit Japan earlier this week.
The North Bay can expect to see rain and strong winds beginning Monday afternoon, spreading south that night, according to the National Weather Service.
In San Francisco, residents are being warned of the possibility of flooding and downed tree limbs. That city's Public Works Department is offering free sandbags at its operations yard and will be posting updates on flooding and tree damage and providing tips on how to prepare for the storm on its website: www.sfgov.org/dpw.
For the Tri-Valley, high temperatures today and Sunday are expected to reach into the high 70s and low 80s with the thermometer expected to drop into the low 70s by Sunday. Variable winds of 5 to 10 mph are expected for both days.
Rain is forecast for the Tri-Valley on Monday, though more likely on Tuesday. Current forecasts do not include this area in the possibly more severe wind and storm forecasts now being made for the coastal areas.
