SAN FRANCISCO, CA – Coastal communities across the San Francisco Bay Area and Monterey Bay face an extended period of potentially dangerous flooding and powerful ocean waves beginning Thursday, November 5, with water levels capable of inundating low lying roads and waterfront areas.
According to the National Weather Service's San Francisco Bay Area office, a coastal flood advisory remains in effect through Friday, November 13, as elevated water levels combine with peak high tides across San Pablo Bay, San Francisco Bay and southern Monterey Bay.
Forecasters warn that up to 1.6 feet of water above ground level could affect vulnerable shoreline locations, particularly near tidal waterways, docks, walkways and coastal roads.
The flooding threat is especially concerning for motorists traveling through low lying waterfront areas. Some roads could become temporarily impassable during high tide cycles, potentially requiring closures or detours.
Dangerous Waves Could Reach 16 Feet A separate National Weather Service statement warns of hazardous beach conditions through Monday, November 9, along Pacific Coast beaches.
A prolonged northwesterly swell is expected to generate breaking waves reaching 12 to 16 feet , creating an increased risk of sneaker waves and strong rip currents.
These powerful waves can unexpectedly sweep across beaches, rocks and jetties, potentially pulling people into the ocean with little warning.
Coastal areas near San Francisco, Santa Cruz and Monterey are among the locations where residents and visitors should exercise caution.
What Residents Should Know The National Weather Service urges people to avoid entering floodwaters, driving around barricades or attempting to cross submerged roads.
Beachgoers should remain away from piers, jetties and exposed rocks while hazardous surf continues.
Property owners in flood prone shoreline neighborhoods should consider protective measures ahead of peak high tides.
Residents planning coastal travel through November 13 should monitor updated National Weather Service advisories, particularly when traveling near waterfront roads or visiting beaches.
