Heading into the weekend, the National Weather Service San Francisco advises locals and visitors to maintain caution near harbors and inlets due to subsiding. However, dynamic tidal conditions are still present following Wednesday's tsunami. Marine layer conditions are also expected to contribute to patchy drizzle along coastal areas. The NWS has underscored that "Seasonably mild weather persists into the weekend" with "typical summertime weather" on the docket for the Bay Area.

For those planning to enjoy the coastline, despite an expiration of the Beach Hazards Statement, fluctuating water levels merit a prudent approach to beachside activities. "As always, please continue to exercise caution on, in, or near the ocean today as water levels continue to fluctuate," stated the National Weather Service in their latest report. Winds are also on San Francisco's atmospheric menu, with gusty onshore breezes along the coast and particular areas such as gaps and passes expected Sunday and Monday.

Aviation is returning to standard operations, with variable visibility conditions improving throughout the day. The marine layer is predicted to compress by this afternoon, facilitating VFR (Visual Flight Rules) achievement for most terminals. Nonetheless, IFR ceilings are anticipated to return tonight in certain areas, as reported by the National Weather Service.

Mariners are gearing up for gale-force gusts, prompting advisories about fresh to strong northwesterly breezes. According to the NWS, these conditions will take hold around Point Reyes and Point Sur by Sunday afternoon, leading to "moderate to rough seas" expected to last through Monday.

Regarding public advisories, small craft advisories remain in place along various points of the California coastline, urging smaller vessels to exercise caution or postpone outings due to expected adverse sea conditions. "Small Craft Advisory from 3 PM this afternoon to 9 PM PDT this evening for Pt Arena to Pt Reyes 0-10 nm," cautions the NWS, and several other areas are facing similar advisories.
