Red Flag Warning for parts of the Bay Area
Red Flag Warning: An official Red Flag Warning is active from 10:00 PM tonight through 11:00 AM Friday across the North Bay Interior Mountains. Diablo Winds: A classic weather setup is unleashing a dangerous Diablo Wind event over the ridges. The highest mountain peaks around Mt. Saint Helena have already clocked extreme wind gusts between 50 and 60 mph, and these powerful, bone-dry gusts will mix down to lower altitudes overnight through late Friday morning. Extreme Fuel Dryness: It has not rained in the North Bay since September 4th, meaning mountain vegetation and brush are critically parched and primed for explosive fire growth if an ignition occurs. Abstain from any outdoor activities that could cause a spark. Mountain Nights: A severe thermal belt above 1,000 feet will trap hot air over the hills tonight. While lower valley floors cool off, mountain ridges will suffer from critically poor relative humidity recovery and unseasonably warm overnight lows, offering zero physical relief from the heat. Regional Microclimate Temperature Span Tonight: Immediate Pacific Coast: Mid 50s Bayshore Cities (SF/Oakland): Mid 50s Inland Valleys: 50s - Low 60s Friday (Tomorrow's Daytime Highs): Immediate Pacific Coast: 75° to (Santa Cruz) 85° Bayshore Cities (SF/Oakland): 78° to 88° Inland Valleys & Mountains: 88° to 98° (Hottest- Santa Rosa and Gilroy)

Unseasonably cool weather continues
Happy Sunday! Unseasonably cool weather continues today and Monday. Chilly mornings with temps dipping into the 40s inland. will be followed by highs in the 60s and 70s. Beach Hazard Statement: Large surf, strong rip currents and sneaker waves create dangerous beach conditions through Monday evening. Coastal Flood Advisory: Low lying flooding is possible for areas adjacent to the bay during high tides, with advisories extending into Tuesday and Wednesday for some locations. Dry weather continues followed by a warming trend that kicks off on Tuesday. Highs Thursday through Saturday could reach the 80s to lower 90s as high pressure builds.

Sweater weather returns
Happy Saturday night! A mostly dry cold front sweeping across Northern California has dramatically tightened regional pressure gradients. The Gust Peak: Northwest winds will roar across the region through Sunday evening. Expect widespread sustained winds of 15 to 25 mph, with frequent gusts hammering between 35 and 45 mph directly through favored mountain gaps, coastal passes, and wind-prone bayshore channels like the San Bruno Gap and Altamont Pass. Active Marine & Coastal Advisories Beach Hazards Warning (Active through Monday Evening): A dual, long-period ocean swell is generating dangerous breaking waves up to 16 feet. This creates a critical, life-threatening risk for sudden, massive sneaker waves and intense rip currents. Do not approach the surf line. Stay completely off beach sand, coastal rocks, and jetties. Never turn your back on the ocean. Coastal Flood Advisory (Active through 3:00 PM Tuesday): High astronomical tides will force minor saltwater flooding into low-lying shoreline trails, docks, sidewalks, and parking lots along the San Francisco, San Pablo, and Monterey Bays during the highest late-afternoon tide windows.Avoid parking in low-lying bayshore lots over the next few days. Regional Microclimate Temperatures Immediate Pacific Coast: 56°F to 62°F Bayshore Cities (SF/Oakland): 63°F to 69°F Inland Valleys & Mountains: 70°F to 76°F Have a wonderful Sunday!

Cooler, windy, dangerous surf today
The Bay Area is settling into a much cooler fall pattern this weekend, with gusty winds, and a mix of morning clouds and afternoon sunshine for Fleet Week Festivities in SF. Weekend highs will generally reach the 60s and 70s, with the warmest conditions inland. BEACH HAZARD STATEMENT for Beachgoers as long-period southerly swell is increasing the risk of sneaker waves and strong rip currents. A second, powerful northwesterly swell is expected to arrive Sunday, with breaking waves potentially reaching 16 feet. COASTAL FLOOD ADVISORY until Tuesday for vulnerable coastal and Bay shoreline locations during high tides. The cooler pattern will continue into early next week as an upper-level trough keeps temperatures below seasonal averages. There’s a slight chance for a few light showers Sunday-Monday. High pressure is expected to build back into the region by midweek, bringing drier conditions and a gradual return to warmer daytime temperatures.
