The National Weather Service has issued a coastal flood advisory for low-lying parts of the Bay Area from Tuesday morning through Sunday afternoon due to anticipated “King Tides,” which are expected to be among the highest of the year.
The advisory is in effect from 6 a.m. Tuesday until 3 p.m. Sunday for the San Francisco Bay shoreline and North Bay interior valleys. Forecasters expect minor flooding in vulnerable parking lots, parks, and roadways during high tides.
According to the California Coastal Commission, King Tides occur when the gravitational pulls of the sun, moon, and Earth align. When combined with storms, these tides can significantly elevate water levels, posing a risk of damage to coastal property and infrastructure.
In San Francisco, tides are predicted to be approximately one foot above normal at the following peak times:
* Tuesday at 8:24 a.m.
* Wednesday at 9:04 a.m.
* Thursday at 9:48 a.m.
* Friday at 10:35 a.m.
* Saturday at 11:25 a.m.
* Sunday at 12:17 p.m.
Officials note that high tide timing can vary by up to 90 minutes along the Pacific coast and throughout the Bay.
In addition to the flood advisory, a separate beach hazard statement is in effect through Wednesday evening for the coastline between Sonoma and Monterey counties. The Weather Service warns of dangerous conditions, including breaking waves of 10 to 14 feet, powerful sneaker waves, and strong rip currents. Visitors to coastal areas are urged to use caution and stay off rocks and jetties.
