A U.S. Highway 101 off-ramp near Mill Valley is closed because of high-tide flooding, according to the California Highway Patrol.
The sun and moon’s gravity align Monday to create the highest tides of the year, known as King Tides, potentially flooding low-lying roadways, and leading to unusual sights around docks, piers, and beaches in the San Francisco Bay Area.
It’s a flow of water bigger than the mighty Mississippi River – 390 billion gallons of water move in and out of San Francisco Bay twice a day, creating an engineering challenge for the designers of the new Bay Bridge.
A surge Thursday of unusually high tides flooded roadways and parking lots along the Bay Area coast.
Forecasters are urging people enjoying the Northern California coast to be careful as high tides and big waves hit the region’s beaches during the next few days.
A high surf advisory will go into effect Saturday evening and continue throughout the weekend along the Bay Area coast, according to the National Weather Service.
