A Tsunami Advisory remains in effect for the California coast, including all coastal regions in the Bay Area and Central Coast. Initial tsunami waves have been observed along the coastline with additional fluctuations in wave heights to continue until further notice. Dangerous and powerful currents are expected in the ocean and at the beach. Stay away from the water! Stay away from beaches and waterways! Remain away from shore until local officials say that it is OK to return. Do NOT try to go to the coast to take photos! You will not just put yourself at risk, you will put the people who have to rescue you at risk. Tsunami hazard zone maps are available at https://www.conservation.ca.gov/cgs/tsunami/maps.
