King Tide Advisory Brings Coastal Flood Risk – CBS San Francisco

SAN FRANCISCO (CBS SF) — Cold coastal flooding could occur across the Bay Area Saturday through Monday as the region’s highest tides of the year hit the coastline, according to the National Weather Service.

These tides are called royal tides, which occur when the Earth, moon, and sun align to reach the astronomically strongest tides in the ocean.

Historically, these tides flooded low-lying areas like parks and roads along the San Francisco Bay coastline and specific points along the Pacific coast, like Elkhorn Slough.

The weather service lists minor risks of coastal flooding along the North Bay, East Bay, South Bay, Peninsula and Central Coast.

The weather service also predicts the tide will peak at 7.21 feet on Sunday at 10:11 a.m., although all three days will see tide heights above 7 feet.

Beachgoers, sailors and other members of the community are encouraged by the weather service to check local tide levels before approaching the water, as levels can change rapidly during this time.
