Tsunami Advisory issued on the West Coast; people asked to stay off beaches, out of water

Tsunami waves of one to two feet were expected to hit the San Francisco coastline at around 8:10 p.m. and peak at 9:09 a.m., bringing strong rip currents, coastal flooding and inundation of low lying areas.

Some evacuations have begun in Santa Cruz Harbor due to flooding. Photos and videos shared to social media show a Santa Cruz parking lot filling with water.

Marin County Sheriff has reported rapid tsunami surges of three feet and warned residents to avoid traveling to coastal areas to observe the waves. "Currents are extremely strong and unpredictable," officials said.

The Hunga Tonga-Hunga Ha'apai volcano erupted Saturday morning 40 miles off the coast of Tonga.

The National Weather Service warned that water level surges can overwhelm and overtake people and pull them out to sea.
