San Franciscans living along the Bayshore areas of the San Francisco and San Pablo Bays should prepare for minor coastal flooding, which is expected later this evening. The National Weather Service in San Francisco issued a Coastal Flood Advisory, effective from 11 PM Thursday to 2 AM Friday. Officials warn residents and travelers to avoid driving around barricades or through water if the depth is unknown. Marin County's bayside spots like Sausalito and the Sausalito-Mill Valley Bike Path may experience localized flooding.

The normal weather pattern with its famed "June Gloom" is set to persist until next week. Nevertheless, things could change slightly over the weekend into early next week, with a weak upper-level trough potentially inviting some unsettled conditions. According to the National Weather Service, San Francisco's Area Forecast Discussion, weather models don't currently predict notable precipitation or thunderstorms due to insufficient instability.

For Bay Area travelers, low marine clouds are hanging around this morning, with forecasts indicating a clearing up by late morning. This is despite a slight drizzle lingering in the area. The marine layer's compression helps to limit the extent of the stratus clouds, but IFR/MVFR ceilings are expected to return tonight into Friday morning, with conditions improving towards the afternoon.

Mariners should take note of continued fresh to strong northwesterly breezes, which could reach near-gale force gusts through Friday. The National Weather Service advises that gale-force gusts may particularly affect coastal jet regions near Point Reyes and Point Sur this afternoon and evening. Elevated wind conditions are expected to soften over the weekend, but regardless, small craft advisories and gale warnings have been posted for select offshore areas.
