Since the tsunami hit beaches in Los Angeles and Orange counties around 2 a.m., police in several coastal cities reported no activity or calls for service to the water. Weather experts warned that fluctuations in the tide could continue Wednesday.

A tsunami advisory was downgraded to a watch for Southern California coastlines after little activity was seen overnight, but weather experts warned that fluctuations in the tide could continue throughout Wednesday, July 30, following an 8.8-magnitude earthquake near Russia.

Tide gauges recorded tsunami waves along the Northern California coast, including in San Francisco and Monterey, according to the weather service.
