WIND ADVISORY IN EFFECT FROM 11 PM SUNDAY TO 11 AM PDT MONDAY for The Santa Cruz Mountains, North Bay Interior Mountains, Eastern Santa Clara Hills, and East Bay Hills. Expect North to northeast winds 15 to 30 mph with gusts up to 50 mph expected. Local gusts up to 60 mph. Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result. Winds this strong can make driving difficult, especially for high profile vehicles. Use extra caution.

⚠️ ELEVATED FIRE WEATHER THREAT THROUGH MONDAY We are tracking a period of elevated fire weather risk across the Interior Bay Area and Central Coast through Monday afternoon. While the overall risk level is currently "Minor," the combination of dry fuels and gusty winds creates a recipe for rapid fire spread if an ignition occurs. What to expect: Humidity: Very dry conditions with RH values between 10-25%, especially in the higher terrain across the region. Winds: Sustained winds of 20-30 mph, with local gusts reaching 45-50 mph. Impacts: Rapid rates of spread possible on any wind-and-terrain aligned starts. How you can help: Practice "One Less Spark" today. Avoid using lawnmowers or grinders in dry vegetation, ensure tow chains aren't dragging on the pavement, and never leave a campfire unattended.

HEADS UP: If you’re planning a trip to the coast this weekend, please stay alert! 🌊 A Beach Hazards Statement is in effect from now through Monday morning for west-facing beaches along the Pacific Coast. Strong northerly winds are set to generate very rough conditions, including powerful rip and longshore currents. What you need to know: Safety First: Rough seas can suddenly sweep people off beaches, rocks, and jetties. Stay off the rocks! Cold Water: Strong upwelling will cause water temperatures to plunge—expect a shock if you enter the water. Tidal Swings: Large tidal swings could trap walkers by cutting off exits. Erosion: Intense waves may make coastal terrain and cliffs unstable. Respect the power of the Pacific: Stay back from the water’s edge and NEVER turn your back on the ocean.
