A new storm will bring rain, wind and possible flooding to the Bay Area on Thursday afternoon but is expected to taper off by Friday morning, according to the National Weather Service.
Heavy rain and winds will likely hamper the afternoon commute, and forecasters are calling for up to 1.5 inches of rain in the region's valley areas and up to 4 inches in the hills.
Steady southerly winds of between 15 and 30 mph will push through the Bay Area ahead of the storm, with possible gusts of up to 40 mph, according to the weather service.
The storm's main impacts will hit Thursday morning in the north bay and will move over the entire region in the afternoon and evening. It's expected to linger through the pre-dawn hours of Friday.
On the Midpeninsula Thursday, the chance of rain is predicted to be 90 percent. There will be showers after 10 a.m. and southeast wind around 18 mph, with gusts as high as 24 mph. Rainfall totaling a 0.25 to 0.50 inches is possible.
Showers will continue Thursday night, resulting in an additional 0.25 to 0.50 inches of rain, the weather service is estimating.
Urban flooding is likely around the Bay Area during the storm, especially in Marin County, according to the weather service.
The storm will coincide with so-called "king tides," naturally occurring and very high tides that can contribute to flooding, especially along coastal areas and near creeks and estuaries.
The high tide at the Golden Gate Bridge will arrive around noon Thursday, just as the heaviest rains are expected, according to the weather service.
The weather over the weekend will be mostly clear.
