San Francisco, California – Minor coastal flooding is expected along the San Francisco Bay and San Pablo Bay shorelines late Tuesday night, prompting a Coastal Flood Advisory from the National Weather Service.
According to the Weather Forecast Office in San Francisco, high tide will reach 6.88 feet at 12:02 a.m. Wednesday, with the advisory in effect from 10 p.m. Tuesday through 2 a.m. Wednesday. Areas at risk include low-lying bayshore locations from San Jose and Palo Alto up through Oakland, San Francisco, and Napa.
The advisory warns of potential flooding in parking lots, parks, and low-lying roads, with isolated closures possible.
