San Francisco, CA – Rising tides could push water onto low-lying roads, waterfront properties and vulnerable shoreline areas around San Francisco Bay through Thursday, Oct. 29, as a Coastal Flood Advisory remains in effect across portions of the Northern California coast. The National Weather Service warns that inundation reaching 1.9 feet above ground level is possible in some locations, creating concerns for drivers, waterfront businesses and residents near tidal waterways. The threat extends beyond San Francisco into portions of Monterey Bay and the Big Sur coastline.
According to the National Weather Service in San Francisco, the Coastal Flood Advisory remains in effect until 3 p.m. PDT Thursday, covering the San Francisco and North Bay interior valleys, San Francisco Bay shoreline, Northern Monterey Bay, Southern Monterey Bay and Big Sur Coast.

Officials also warn that rising water may travel farther up beaches than usual, potentially restricting escape routes along exposed coastal areas.
Highest Tides Expected Tuesday and Wednesday The advisory identifies several periods when unusually high tides could increase flooding concerns. At the San Francisco tidal gauge, water levels are forecast to reach approximately 1.5 feet above normal Sunday at 11:07 a.m., followed by 1.6 feet above normal Monday at 11:39 a.m. Those levels are expected to increase further Tuesday, when the predicted tide reaches 1.9 feet above normal at 12:15 p.m…
