SAN FRANCISCO (CBS / AP) — The California coast, including parts of the Bay Area, will experience unusually high tides and possible minor flooding in some areas through Sunday morning, the National Weather Service said Friday.
The astronomical tides, also known as King Tides, will occur each morning, followed by very low tides hours later each afternoon, the weather service said. The peak will be on Saturday.
Coastal flood advisories were issued for low-lying areas of the San Francisco Bay shoreline and Humboldt Bay on the north coast.
King Tides will impact the area the next 3 days & bring some of the highest & lowest tides of the year.
These tides will bring localized flooding to several low lying areas along the SF bayshore during high tide during the mid to late morning each day. https://t.co/TZ4mWUYPEf pic.twitter.com/jC4kQWSZVF

In Southern California, a beach hazards advisory was issued for portions of the coast along Los Angeles, Ventura, Santa Barbara and San Luis Obispo counties but no significant damage was expected.
The unusually high tides occur when the moon, Earth and sun come into alignment while the moon is closest to Earth and Earth is closest to the sun, the weather service said.
The California King Tides Project is encouraging anyone near the coast to send in photos of the high tides as part of its effort to increase understanding of what the state will experience as climate change causes sea level to rise.
