Storm conditions today throughout the Bay Area and Monterey Bay region are expected to peak later this afternoon and into the early evening, according to the National Weather Service.
Strong gusty winds coupled with moderate to heavy rainfall are anticipated today, which could result in more coastal flooding. The strong winds could also cause downed trees, resulting in more power outages and blocked roads.
Chances of thunderstorms later tonight are low but possible, weather service officials said.
Weather service officials have also issued a flood warning for the Russian River near Guerneville, and the Napa River in areas near St. Helena and Napa.
In addition to the wet weather, king tides will occur today through Thursday. The tides are a naturally occurring phenomenon that occurs when there is an alignment of the gravitational pull between the sun and moon, causing high astronomical tides, according to the weather service.
The tides, along with the storm surge and rain runoff, could result in flooding in coastal and low-lying areas.
The rain is expected to ease up later tonight and into early Wednesday morning, with scattered showers expected after that, weather service officials said.
After Wednesday, a drying and cooling trend is expected to come into the Bay Area and Monterey Bay region, going into the weekend and early next week, according to the weather service.
