San Diego currently under Tsunami Advisory


In an event rarely seen in Southern California, the waters of San Diego Bay rose by 1.4 feet on Saturday due to the arrival of tsunami waves produced by an underwater volcano that erupted in the Pacific off Tonga, according to the National Weather Service.

The water also rose by 6 inches in La Jolla. Forecasters say the bay magnifies the tide, which is likely responsible for the higher reading.


“It looks like things have topped out, but there’s still a lot of variabilities,” said Brandt Maxwell, a forecaster at the weather service office in Rancho Bernardo. “We could still have unusual currents, including in places where you normally don’t see them.”

At about 11 am this morning, Port San Luis in San Luis Obispo Bay on the Central Coast had logged the largest surge in California with a 4.3-foot increase in water level, according to the weather service. Videos on social media showed flooding surges in Santa Cruz, putting at least one parking lot underwater.
