The storms pose significant risks, particularly along the coast, where large waves and storm surges could lead to dangerous conditions. The NWS warns of strong rip currents, sneaker waves, and potential coastal flooding, especially during peak high tides. Low-lying areas around San Pablo, San Francisco, and Monterey Bays may experience inundation. Inland areas, including the San Joaquin-Sacramento River estuary, could also face record-breaking flooding this winter. The combination of king tides, El Niño effects, and storm surges increases the likelihood of significant coastal erosion and flooding. The risk of drowning is high, and residents are urged to avoid beaches and coastal areas.
