A tsunami advisory was issued Saturday morning along the West Coast, including parts of the Bay Area, as weather officials told residents to avoid coastal waters.
The National Weather Service said there could be up to a couple feet of flooding at beaches at harbor areas in the Bay Area, including in San Francisco and Berkeley, during the morning hours.
The announcement prompted the city’s department of emergency to order residents to stay away those areas.
“If you are on a beach, harbor or marina dock, or pier, and you cannot self-evacuate, call 911 for evacuation assistance now,” the department said in an alert. “Stay away from San Francisco beaches, harbor and marina docks, and piers until the city issues an official notice that it is safe to return.
The Berkeley Fire Department, meanwhile, ordered the mandatory evacuation of residents living at or near the city’s Marina neighborhood due to similar flooding risks.
#TsunamiAdvisory remains in effect for the #WestCoast, with peak tsunami wave heights of 1 to 2 feet possible. Main impacts expect to be strong rip currents, coastal flooding, and inundation of low lying areas is possible. Move to higher ground. #CAwx

Weather officials are attributing the tsunami risk to a volcanic eruption early Saturday that struck Tongatpu, an island in Tonga, triggering tsunami warnings up and down the West Coast.
