Northwesterly winds will increase throughout the day with gusts up to 35–45 mph along the coast, across the higher elevations and ridgelines, and favored gaps and passes. The Salinas Valley will see an increase in winds as well, with gusts up to 25–35 mph favoring the northern half of the valley.

THE FORECAST HIGHS FOR FRIDAY WILL BE SIMILAR THURSDAY`S, PERHAPS A FEW DEGREES WARMER. [DISC] Saturday into Sunday, the aforementioned upper level trough digs and deepens into the Intermountain West and into then into the Great Basin. This will bring an additional burst of winds, which will have a more north-northwest to northerly component. Peak gusts up to 35–45 mph along the coast, across the higher elevations and ridgelines, and favored gaps and passes. Locally higher perhaps close to 50 mph are possible for points at the immediate coast and the highest ridge points. The Salinas Valley will be gusty too, with gusts up to 25–45 mph favoring the northern half of the valley. Elsewhere, northerly winds may gust up to 20–35 mph. Timing for the strongest winds currently looks to be between late Saturday morning through early Sunday morning, peaking Saturday afternoon through the evening. Northerly winds, means a burst of drier air coming our way leading to elevated fire weather conditions for the interior Bay Area and Central Coast. ∨ SATURDAY INTO SUNDAY, THE AFOREMENTIONED UPPER LEVEL TROUGH DIGS AND DEEPENS INTO THE INTERMOUNTAIN WEST AND INTO THEN INTO THE GREAT BASIN.

NORTHERLY WINDS, MEANS A BURST OF DRIER AIR COMING OUR WAY LEADING TO ELEVATED FIRE WEATHER CONDITIONS FOR THE INTERIOR BAY AREA AND CENTRAL COAST. [DISC] The pattern looks to shift slightly on Monday as the trough moves eastward, which will continue ease the northerlies throughout the day. By Tuesday, onshore flow returns as troughing continues to travel eastward and high pressure builds in over the eastern Pacific. Agree with the prior shift's thinking in that the temperatures may be a bit too warm for Wednesday–Friday. Guidance shows ridging holding over the Pacific, while an upper trough forms southwest of California. ∨ THE PATTERN LOOKS TO SHIFT SLIGHTLY ON MONDAY AS THE TROUGH MOVES EASTWARD, WHICH WILL CONTINUE EASE THE NORTHERLIES THROUGHOUT THE DAY.

[AVIA] Beaches… issued at 2:50pm PDT Thursday May 14 2026 ∨ .BEACHES... ISSUED AT 250 PM PDT THU MAY 14 2026 [DISC] A beach hazards statement has been issued for west facing beaches along the Pacific coast from 3pm Friday through 9am Monday due to strong winds over the marine environment leading to hazardously strong wind waves and overall rough seas. Dangerous swimming, boating, and surfing conditions can be expected. Large breaking waves can overpower swimmers resulting in significant physical injury and increase the risk of drowning. Gusts will stay strong along the immediate coast, causing blowing and drifting sand and increased sea spray. Water rescue attempts may be hampered by reduced visibilities from the sea spray. Remember, never turn your back on the ocean. ∨ A BEACH HAZARDS STATEMENT HAS BEEN ISSUED FOR WEST FACING BEACHES ALONG THE PACIFIC COAST FROM 3 PM FRIDAY THROUGH 9 AM MONDAY DUE TO STRONG WINDS OVER THE MARINE ENVIRONMENT LEADING TO HAZARDOUSLY STRONG WIND WAVES AND OVERALL ROUGH SEAS.
