San Francisco, CA – Rising tides could push water across low lying waterfront areas, threatening shoreline roads and coastal infrastructure before a wetter weather pattern arrives Friday.
Up to 1.6 feet of inundation above ground level is possible in vulnerable locations along San Francisco Bay.
According to the National Weather Service in San Francisco, a Coastal Flood Advisory remains in effect until 4 p.m. PST Friday, November 13.
The advisory covers San Francisco, bayshore locations and areas along San Pablo Bay.
Coastal Flood Advisory: High Tides Threaten Waterfront Areas The National Weather Service warns that unusually high tides could flood low lying infrastructure, cause isolated road closures and accelerate coastal erosion.
Rising tides may also carry water farther up beaches than normal, restricting access to some shoreline areas.
Waves can sweep across the shoreline without warning, potentially pulling people into the water from beaches, jetties and docks.
Residents should avoid flooded roads and never drive through barricades.
The advisory identifies several elevated high tide periods at the San Francisco tide gauge.
Tuesday's high tide is projected near 11:04 a.m., approximately 1.5 feet above normal.
Wednesday's high tide is expected near 11:35 a.m., approximately 1.4 feet above normal.
Thursday's high tide arrives near 12:10 p.m., approximately 1.3 feet above normal.
Friday's high tide is expected near 12:49 p.m., approximately 1.1 feet above normal.
These figures describe tide elevations above normal, not water depth on streets.
Thursday and Friday: Rain Adds Another Concern Thursday, November 12, brings partly sunny skies and afternoon temperatures near 71 degrees.
Rain chances increase Thursday evening, with a 30% precipitation probability after 4 a.m. Friday.
Friday, November 13, brings rain and breezy conditions, with temperatures near 67 degrees.
The National Weather Service notes that predicted tides include up to 1.4 feet of surge, increasing the astronomical tide and flooding threat.
Motorists traveling near waterfront routes should check road conditions before departing.
Weekend: Cooler Weather and More Rain Possible Saturday, November 14, brings a chance of rain and highs near 64 degrees.
Sunday remains unsettled, with rain likely and afternoon temperatures near 62 degrees.
No local snow, tornado or freezing precipitation threat is identified in the supplied forecast.
Residents near flood prone waterfront property should continue monitoring official updates, even as the advisory approaches expiration.
