San Francisco, CA – Coastal flooding could affect low lying shoreline communities across the San Francisco Bay Area and California's Central Coast beginning Saturday, October 24, with high tides potentially pushing water nearly 2 feet above ground level in vulnerable locations through Thursday.
According to the National Weather Service NWS San Francisco Bay Area/Monterey office, a Coastal Flood Advisory will take effect at 8 a.m. Saturday for shoreline areas along San Pablo Bay, San Francisco Bay and Monterey Bay, continuing until 3 p.m. Thursday, October 29.
Floodwaters Could Reach 1.9 Feet Above Ground
Forecasters warn that peak high tides could produce up to 1.9 feet of inundation above ground level in susceptible coastal areas and near tidal waterways.
The flooding threat includes waterfront communities around San Francisco Bay, San Pablo Bay and Monterey Bay, where rising water could affect roads, parking areas and flood prone properties.
Although the anticipated flooding is classified as minor, even shallow water can create hazardous driving conditions and disrupt access to low lying coastal roads.
Pacific Coast Advisory Begins Monday
The flooding threat will expand Monday, October 26, when a separate advisory period begins for vulnerable locations along the Pacific Coast.
That advisory is scheduled to begin at 9 a.m. Monday and remain in effect until 3 p.m. Thursday.
Communities along the Central Coast, including areas near Santa Cruz and Monterey, should monitor changing tidal conditions as the week progresses.
Drivers Urged to Prepare for Road Closures
The NWS cautions that minor flooding could lead to temporary road closures in low lying coastal communities.
Motorists should allow additional travel time, avoid driving around barricades and never enter flooded roadways when water depth is unknown.
Residents with flood prone property near shorelines or tidal waterways should take precautions before peak high tides arrive.
The flooding risk is expected to persist across multiple high tide cycles through Thursday afternoon.
