High Tides and Possible Flooding to Continue Through 11/01
The Coastal Flood Advisory has been extended across low-lying coastal and bayfront areas due to elevated water levels around times of peak high tide. Up to 1.9 feet of inundation above ground level is possible near shorelines, parking lots, and tidal waterways. https://www.cortemadera.gov/m/NewsFlash/home/detail/950
TIMING & LOCATIONS:
- Pacific Coast: Extended until 6:00 PM Saturday
- San Pablo Bay, San Francisco Bay, and Monterey Bay: Extended until 6:00 PM Sunday
IMPACTS & SAFETY PRECAUTIONS:
Turn Around, Don't Drown: Do not drive around barricades or attempt to drive through water of unknown depth.
Low-lying coastal roads, walkways, and docks may experience minor flooding during high tide cycles.
Allow extra commute time if traveling near vulnerable shorelines, as some roads may become impassable or closed.
Take precautions now to secure or protect flood-prone property.
Monitor local tide tables and stay tuned for forecast updates: weather.gov/BayArea
Residents and business owners are encouraged to take simple preparedness steps, including clearing debris from gutters, drains, and driveways, securing homes in flood-prone areas with sandbags when appropriate, and avoiding flooded areas. Never walk or drive through water of unknown depth, follow posted road signs, and do not drive around barricades.
