Short term

Issued at 1213 PM PDT Fri Oct 30 2026 (This evening through Sunday)

There remains a slight chance to chance for rain showers across the Central Coast (mainly across interior Monterey County and San Benito County) through this evening. There is also a 5-10% probability of thunderstorms this afternoon and early evening across the mountains of San Benito County, however probabilities remain low at this time. The primary hazards with any isolated thunderstorms that do develop will be lightning, localized moderate/heavy downpours, and gusty/erratic winds.

Tonight, mostly dry conditions are forecast to persist as the cold front pushes into northern California and weakens as at approaches the Bay Area. This feature will bring chances for rain across the Bay Area by Saturday afternoon and into early Sunday morning. Meanwhile, chances for precipitation across the Central Coast from remnant moisture aimed toward southern California.

All that said, the NBM Probabilities of reaching greater than 0.25" (15-35%) reamin highest along the highest through tonight across Monterey and San Bentio. Then by Saturday night across Sonoma County and 15-45% across Monterey and San Benito counties Saturday night into Sunday morning.

From previous forecaster: "A combination of high astronomical tides and surge from thermal expansion and low pressure effects brings the risk of minor coastal flooding along the Bayshore at the San Pablo, San Francisco, and Monterey Bays, and the Pacific coast, at high tide today. At the San Francisco tidal gauge, high tide is expected to be 1.9 ft above normal (7.7 ft MLLW) at 2:39 PM today, 1.5 ft above normal (7.3 ft MLLW) at 3:44 PM Saturday, and 1.0 feet above normal (6.8 ft MLLW) at 3:59 PM Sunday, including around 1.5 ft of surge residual." The Coastal Flood Advisory drops off after high tide on Saturday for the Pacific Coast but remains in effect through Sunday for bayshore locations along the San Pablo, San Francisco, and Monterey Bays.

Long term

Issued at 1213 PM PDT Fri Oct 30 2026 (Sunday night through next Thursday)

Weak ridging builds in from the eastern Pacific Sunday and into Monday in wake of the exiting trough. This will result clearing of clouds regionwide and dry weather conditions Sunday afternoon through Monday afternoon along with a slight warming trend. However, temperatures will generally remain a few degrees below normal.

Tuesday and beyond, there is still a great amount of uncertainty with the forecast. The current forecast indicates a slight chance of rain/rain showers on Tuesday as a trough or cut-off low approaches the Bay Area and Central Coast. That said, the Climate Prediction Center's 6-10 Day Outlook our region in the 33-40% for greater than normal precipitation.
