SAN FRANCISCO, CA – A stronger storm system is expected to impact the San Francisco Bay Area and California's Central Coast on Wednesday, November 18, bringing widespread rain, strong winds, thunderstorms and dangerous high surf as forecasters identify the day as the highest weather risk period of the week.
According to the National Weather Service San Francisco Bay Area/Monterey office, unsettled weather will continue throughout the week, with multiple rounds of precipitation and coastal hazards affecting communities across the region.
The agency has designated Wednesday as a high risk weather day , with a stronger storm expected to bring several potentially hazardous conditions simultaneously.
The unsettled pattern began Sunday, November 15, as rain and high surf moved southward across the region.
Moderate weather risks are expected Monday, November 16, with lingering rain showers and high surf continuing behind the initial frontal system.
Tuesday, November 17, should bring a brief period of lower weather risk, although isolated showers could persist early in the day.
Another round of rain is forecast to move into the region from the north Tuesday night, setting the stage for Wednesday's stronger system.
Wednesday's primary concerns include widespread rainfall, strong winds, thunderstorms and high surf , particularly along exposed coastal areas.
The National Weather Service expects unsettled conditions to continue Thursday, November 19, with additional showers, thunderstorms, strong winds and high surf possible.
Thursday carries a moderate weather risk designation.
Residents across San Francisco, San Mateo, Santa Clara, Alameda, Contra Costa, Santa Cruz and Monterey counties should prepare for changing weather conditions throughout the week.
Coastal visitors are urged to exercise caution near beaches, rocks and exposed shorelines as high surf creates potentially dangerous conditions.
Motorists should remain alert for reduced visibility and hazardous driving conditions during heavier rainfall.
Forecasters encourage residents to monitor updated advisories and forecasts as the stronger midweek storm approaches.
