Bay Area Braces for "King Tides": Flood Advisory Issued

Forecasters have issued a coastal flood advisory for low-lying areas across the Bay Area, anticipating higher-than-normal tides. This advisory is set to remain active from Tuesday morning through Sunday afternoon, warning residents of potential minor flooding.

The "King Tides," caused by the alignment of sun, moon, and earth, are expected to bring tides about one foot above normal, particularly impacting the San Francisco Bay shoreline and North Bay interior valleys. These tides, among the highest of the year, can exacerbate flooding during storms.

In addition to tidal flooding concerns, a beach hazard statement is in effect for the coastline. Visitors should exercise extreme caution due to anticipated 10- to 14-foot breaking waves, sneaker waves, and dangerous rip currents expected through Wednesday evening.
