Hazardous Weather Outlook National Weather Service San Francisco CA 653 PM PDT Thu Oct 4 2018 CAZ507-510>512-051300- North Bay Mountains-East Bay Interior Valleys- East Bay Hills and the Diablo Range-Santa Cruz Mountains- 653 PM PDT Thu Oct 4 2018 This hazardous weather outlook is for elevations above 1000 feet in the San Francisco Bay Area, as well as portions of the East Bay Valleys. .DAY ONE...Thursday night Isolated showers will end by evening. Expect partly cloudy and mild conditions overnight. .DAYS TWO THROUGH SEVEN...Friday through Wednesday An upper trough is forecast to dig inland to the east of our area early in the weekend and settle into the Great Basin by late Saturday. This type of weather scenario in the autumn typically results in breezy northerly winds across much of our region, and locally windy conditions in the hills. Northwest winds are expected to increase along the coast on Saturday afternoon with local coastal wind gusts up to 40 mph possible by late in the afternoon. Then, on Saturday night, winds are expected to subside near the coast, but turn to the north and increase in the hills. Strongest north winds are expected in the North and East Bay Hills from late Saturday night into Sunday when wind gusts of up to 50 mph are possible. A Wind Advisory may be need for the North and East Bay Hills Saturday night into Sunday. Locally windy conditions are possible elsewhere, including the Santa Cruz Mountains and isolated areas near sea level around the Delta and in northeast Contra Costa county. Winds in the hills are forecast to subside by Sunday afternoon, but then increase once again Sunday night into Monday morning. Winds are expected to decrease in all areas by Monday afternoon. These northerly winds over the weekend will bring a much drier airmass into the region. Recent rains have decreased fire weather concerns, especially across much of the North Bay. However, in those areas that received little or no rain, the combination of strong and gusty winds and lowering humidity will increase fire danger, especially by late Sunday. Please continue to monitor latest forecasts concerning this upcoming wind event.
