The National Weather Service (NWS) has issued a Coastal Flood Advisory for the bayside shorelines of San Francisco Bay and San Pablo Bay until 2 AM Tuesday. With higher astronomical tides, the NWS warns of potential minor flooding in low-lying San Francisco Bay Area areas during high tide, according to the National Weather Service.

Total temperatures are expected to dip this weekend, marking a brief respite before the mercury is slated to climb again early next week quickly. The brief cool down is attributed to a transient shortwave trough, which is anticipated to bring not only cooler temperatures but also stronger winds, especially "along coastal and gap areas" later in the evening. However, near-record levels of energy release components in the North Bay point to ongoing concerns regarding fire weather, with near-critical conditions highlighted for the region through Saturday, according to the Area Forecast Discussion by the National Weather Service.

VFR conditions are expected to prevail inland on the aviation front, while coastal stratus and fog may result in IFR-LIFR conditions this morning. Gusts up to 32 knots are possible around the San Francisco International Airport, with onshore winds set to bring in cooler air. Coastal stratus and fog, with the possibility of morning drizzle, are also expected to linger in Monterey Bay, potentially slowing the improvement of MVFR-VFR conditions.

The marine environment will not be spared from this tumultuous weather, featuring "gusty northwest winds continuing over the coastal waters through the weekend" and "gale force gusts mainly across the northern waters," according to the Marine section of the National Weather Service forecast. Mariners should anticipate very rough seas, particularly on Sunday, and exercise caution. In terms of fire weather, the NWS highlights an elevated risk of fire starts inland, with peak gusts up to 30 to 40 mph in some regions, although a full alignment between the elements required for critical fire conditions seems unlikely due to increasing humidity during the period of peak winds.
