California's coastline on alert as record King Tides fuel prolonged flooding from San Francisco to San Diego
THE TAKEAWAY:
Parts of the heavily populated California coast have seen record-high coastal flooding due to King Tides, including Los Angeles, with flooding expected to continue through Thursday.
Record-high tides have been observed in Los Angeles, with water levels reaching 2.54 feet above normally dry ground along some parts of the coast Monday, while coastal flooding is expected from San Francisco south to San Diego.
WHAT IS COASTAL EROSION AND WHY IS IT DANGEROUS?
San Diego and Santa Monica also saw more than 2.50 feet of coastal flooding Monday.
The City of Newport Beach declared a local state of emergency ahead of the flooding and approved a sand replenishment project to build a sand berm along beaches that have been eroded by swells from large Pacific hurricanes earlier this year.
Coastal Flood Advisories and Warnings are in effect from San Francisco southward to San Diego through Friday.
A King Tide is the highest naturally occurring high tide of the year. Even on clear, sunny days with no storm in sight, these extra-high seasonal tides can push seawater back up through storm drains and onto coastal streets.
Unlike Florida and the Southeast coast, King Tides on the West Coast are driven by astronomical factors, namely the full moon, as well as seasonal changes in water temperatures.
WHAT IS A KING TIDE OR PERIGEAN SPRING TIDE?
According to the FOX Forecast Center, residents should expect significant beach erosion, higher-than-average surf and flooding of parking lots and roads.
Low-lying homes and businesses may also be impacted.
