What is a tsunami advisory?
A tsunami advisory is the second-highest alert, under a warning, according to the NWS.
An advisory is when the NWS urges residents to take action.
"A tsunami with potential for strong currents or waves dangerous to those in or very near the water is expected or occurring," the NWS says. "There may be flooding of beach and harbor areas. Stay out of the water and away from beaches and waterways. Follow instructions from local officials."
A tsunami watch is the second-lowest safety alert, according to the NWS.
The weather agency defines a tsunami watch as: "A distant earthquake has occurred. A tsunami is possible. Stay tuned for more information. Be prepared to take action if necessary."
A tsunami warning, the highest alert, is issued when officials say "dangerous coastal flooding" and "powerful currents" are possible.
"A tsunami that may cause widespread flooding is expected or occurring. Dangerous coastal flooding and powerful currents are possible and may continue for several hours or days after initial arrival," the NWS says.
What Bay Area officials are saying
What they're saying
The San Francisco Department of Emergency Management said Tuesday evening that strong, dangerous currents are expected to impact San Francisco beaches, harbors and marina docks.
"San Francisco's public safety agencies are working together to evaluate whether the evacuation of shoreline areas is necessary, and will send out additional alerts as soon as possible," the department said.
Mayor Daniel Lurie said he's monitoring conditions in San Francisco.
"I have been briefed and will continue to monitor the situation closely," Lurie said on X. "Our city departments are coordinated, and our emergency response departments are activated. We are also in touch with our state partners to ensure we can get accurate information to San Franciscans as quickly as possible."
He said San Franciscans should expect strong, dangerous currents that could impact piers, beaches, docks and harbors.
In San Mateo County, officials said tsunami heights are expected to reach less than 1-foot. Officials are urging residents to avoid coastal areas as a precaution, but are not suggesting residents to evacuate.
California State Sen. Mike McGuire said on X that the state is monitoring the tsunami advisory.
