The National Weather Service has issued a Coastal Flood Advisory for the Bay Area due to approaching King Tides.
The advisory is active from 8 a.m. on Friday until 3 p.m. on Sunday, as weather officials anticipate a significant increase in water levels throughout the Bay Area.
"The King Tide is the highest predicted high tide of the year at a coastal location," NWS explained in a Twitter statement. They occur when the orbits and alignments of the Earth, moon and sun combine to produce the greatest tidal effects.
The tides are forecasted to impact the North Bay Interior Valleys and San Francisco Bay Shoreline, and will bring flooding to several low lying areas in San Francisco including lots, parks and roads.
Water levels along San Francisco's Embarcadero are expected to rise five inches, from average high tides of six feet seven inches to seven feet one inch.
Even though King Tides only occur twice a year, officials warned they provide a glimpse into future everyday water levels due to climate change.
