The weather service issued a coastal flood warning along the San Francisco Bay Shoreline that’s in effect through 2 p.m. Saturday. The higher tides than normal will be crashing amid possible isolated thunderstorms, too, Gass said.

Bay Area residents can expect a wet welcome to 2026, as forecasts call for showers to continue through the end of the week.

Rain is in the forecast on Wednesday, beginning in the South Bay and Peninsula in the morning, which will then spread to the rest of the Bay Area by afternoon. And that rain is definitely being forecast for New Year's Eve and New Year's Day, where there will also be a lot of wind, according to the NWS.

The rain is expected to start Tuesday night or Wednesday morning and continue “off and on” through the weekend.

The Bay Area is expected to ring in the New Year with a slight warming trend, a pair of storms and the possibility of some bay-side and coastal flooding.

Most of the greater Bay Area will have a chance of rain on Wednesday, while cloudy skies and fog will prevail at night, forecasters say.

The Bay Area could be in the path of an atmospheric river this weekend, with forecast models trending toward a wetter, multiday storm.
