The first waves hit California beaches around 5 a.m. at low tide. High tide is expected to hit shortly before noon and may reach a foot higher than average. This increase is similar to what is simply considered rising tide. Waves may grow to be as high as three feet. The advisory was canceled around noon, according to the National Weather Service.

Residents along the coastal areas were urged to stay away from the beaches, harbors and marinas - but there were no evacuation orders.
Advisories are lower level notifications than warnings. A tsunami advisory alerts the public to expect some stronger currents and a slight rise in the ocean level.
