.SHORT TERM... (This evening through Tuesday) Issued at 1257pm PDT Monday September 25 2023

Current radar showing light showers stretching into Mendocino county, slowly making their way down the coast. Not much change to the overall thinking through this evening. Retaining a slight chance of rain across the Bay Area with higher chances for the North Bay. Totals by Tuesday morning look to be in the 0.1-0.25" range across the North Bay, with locally up to 0.5-0.75" in the higher terrain along the Napa/Lake/Sonoma county lines and the Sonoma coastal range. Further south across the Bay Area, totals will be less than stellar, with only a few hundredths of an inch in the forecast. Rain will gradually end across the region late tonight/early Tuesday morning.

Long Term
(Tuesday night through next Sunday) Issued at 1257pm PDT Monday September 25 2023

Slight warm up into midweek with afternoon highs getting back to normal as zonal flow prevails following the exit of the upper trough. Mostly quiet into the weekend with only pleasant and seasonally normal weather expected.

By next weekend, ensemble guidance shows good agreement in an additional trough moving into the Pacific Northwest and down the crest of the Sierra. Watching this scenario as a potential offshore wind event for the North Bay, pending details regarding the placement of the low. Considerable uncertainty still exists regarding how far west the upper low will set up. As of this morning, the trend was slightly westward, which would result in a more moist scenario and weaker offshore winds. Will be following closely to increase messaging as needed. One silver lining of this paragraph is that the North Bay will have had at least some rain out of the current event, and the Energy Release Component of fuels in the Mid-Coast region remains below average for this time of year. Stay tuned for the most up-to-date info as confidence in possible scenarios increases over the next few days.

(Tonight through next Saturday) Issued at 306pm PDT Monday September 25 2023

Fresh to strong breezes over the northern outer waters, diminishing throughout the night as winds turn from the south to the north. Fresh to strong breezes develop tomorrow across the southern waters, with gale force gusts possible in the coastal jet near the Big Sur coast. Northwest swell from a low off the coast of the Pacific Northwest is arriving in the coastal waters. The worst conditions will be tomorrow with 12-15 ft seas in a 15 second NW swell. A small craft advisory is in effect for all unprotected waters.

Issued at 507am PDT Monday September 25 2023

A High Surf Advisory is in effect from 5am to 11pm Tuesday due to large breaking waves generally around 12 to 16 feet, with locally higher conditions around 15 to 20 feet at steep-sloped beaches. Northwest facing beaches are most at risk for these hazardous conditions.

These large breaking waves are generated by large northwesterly swell resultant from an approaching storm. Conditions at beaches will be dangerous for swimmers, surfers, and beachgoers. If planning to visit a beach, caution is advised, as large waves can sweep across beaches with no warning, pulling people into the ocean from jetties, beaches, and rocks. Remember to never turn your back on the ocean, and check local conditions such as tides and currents before visiting.

Exercise caution even after the high surf advisory has ended, as energy in the ocean can be slow to diminish and large waves may continue to be present afterwards until fully dissipated.
