Wet weather will mark the weekend and the coming week as a cold front passes through the region, along with temperatures that are decidedly more autumnal.
Meteorologists on Friday noted at times heavy downpours and wind gusts of up to 55 to 65 mph in some higher elevations and said the storm resulted in downed trees, isolated power outages and minor flooding.
Motorists are warned to use extra caution when driving and to stay clear of downed power lines. Rainfall Friday contributed to minor flooding in low-lying and poor drainage areas and water over roadways, the weather service advised.
Light rain and gusty winds are forecast for the Bay Area and Central Coast beginning Friday through next week, the weather service said. While Saturday will be mostly dry around the Bay Area, a second storm is forecast to move through the region on Sunday with rainfall amounts expected to be similar to Friday’s, according to forecasters. On Friday the Oakland area saw 0.82 inches of rain in 12 hours, according to preliminary reporting by the weather service.
A third storm is also likely in the middle of next week.
In Piedmont daytime temperatures were expected to hover between 58 and 60 degrees over the weekend and then fall into the high 50s during the week, according to the weather service. Overnight lows were forecast to drop to the low 50s on the weekend and then fall again on Monday evening to a chillier 45 degrees, with overnight temperatures in the mid-to-high 40s persisting throughout the week.
Coastal areas of Northern California should also brace for dangerous ocean conditions this weekend, the National Weather Service said Thursday. A coastal flood advisory is in effect through 4 p.m. Friday.
A high surf warning for Pacific Coast beaches along the Central Coast and Bay Area due to dangerously high waves is in effect from 6 p.m. Friday through 4 a.m. Sunday. Some waves could reach 50 feet at sites like Mavericks near Half Moon Bay and could be between 25 and 30 feet elsewhere along the Northern California coast, according to the weather service. These waves can easily overpower swimmers or pull people into the ocean from the beach, jetties, and rocks.
