Thunderstorms expected across San Francisco Bay Area for most of the weekend

The San Francisco Bay Area will be seeing more rain and thunderstorms on Saturday and through part of Sunday, with a chance of isolated weak tornadoes.

According to the National Weather Service, Saturday will have the greatest potential for thunderstorms. Residents can expect "strong and erratic winds, brief heavy rain, small hail, and isolated waterspouts."

The storm impacts began in the afternoon, and moved from north to south across the Bay Area. There was a risk of up to 50 mph wind gusts and isolated weak tornadoes, the NWS said. 

The NWS issued several special weather statements across the area for pea-sized hail and wind gusts. Some of those areas includes San Francisco, San Mateo, Redwood City, Novato and Fairfax. 

Some more thunderstorms are expected across parts of the Bay Area on Sunday morning. 

So far, over the past 24 to 36 hours, there has been an inch and a half of rain in the highest elevations of the Santa Cruz mountains, nearly an inch in Santa Rosa, just over half an inch in San Francisco and Napa, and slightly less in Concord.
