The Sacramento area could receive up to an inch of rain Friday as the first of two storms blows through the region.
The National Weather Service forecasts a 100 percent chance of rain, whipped by 11 to 16 mph winds with gusts of up to 24 mph during the day. A special weather statement warns of slick roads with pooling and flooding, creating a potential for spinouts and accidents during the morning commute. Winds may bring down small branches and weakened trees, blow loose objects and cause power outages.
“If you have some Halloween decorations up already, you might want to bring them inside or tie them down because breezy winds could send those goblins and ghosts flying,” said Courtney Obergfell, National Weather Service meteorologist.
High winds and soaking rain are projected for Northern California through the weekend.
The chance of rain drops to 40 percent Friday night and to 30 percent during the day Saturday.
The next wave of rain is expected to arrive Saturday night and continue through Sunday, before tapering off Monday.
A high near 66 degrees is forecast for the Sacramento area Friday, with an overnight low around 57 degrees. The high Saturday is expected to be near 71 degrees.
In the Sierra, including the Truckee and South Lake Tahoe areas, a high-wind warning is in effect until 11 a.m. Friday, with winds of 20 to 35 mph forecast and gusts up to 65 mph. Rain is forecast through the weekend, with rain and snow possible Monday. A high near 55 degrees is projected for Truckee on Friday with an overnight low around 39 degrees.
In a Periscope chat by the Sacramento office of the weather service, meteorologists briefed Northern Californians about the oncoming storm:
“In terms of rain, we are looking at anything from a half inch to 1 1/2 inches in the Valley from the first wave, alone,” said meteorologist Brooke Bingaman. “The mountains could get up to 4 inches of rain.
“For the second wave, we won’t get quite as much in the Valley, most likely less than an inch. But with the second wave, we could see the snow levels lower into the passes. We are not expecting a lot of snow there, but even a little snow can cause some impacts.”
She said winds could blow hard at times, primarily north of Marysville.
