The Bay Area is preparing for the second atmospheric river storm to soak the region this rainy season and alleviate the dire drought conditions in Northern California.

There will be a slight chance of rain on Friday night into Saturday morning, with less than 0.10 of an inch forecasted in the North Bay, according to the National Weather Service.

Fog is also impacting parts of the Bay Area on Friday morning, reducing visibility in the East Bay and North Bay valleys and possibly affecting morning commute.

An atmospheric river, a moisture-rich narrow storm, is expected to arrive late Sunday and bring widespread rain to the Bay Area on Monday night through Tuesday with lingering showers on Wednesday. The Pacific Northwest will bear the brunt of the storm as it moves inland over Oregon and Washington on Monday. The Center for Western Weather and Water Extremes at UC San Diego has classified the upcoming storm as a 1 on a scale to 1 to 5, with 5 being the strongest.

The rainfall will pale in comparison to the Oct. 24 atmospheric river, which was the strongest storm in recent years and led to the wettest October day on record for San Francisco.

“It’s not as big as the last one,” said National Weather Service meteorologist Matt Mehle. “It’s beneficial rain. We’re still in a drought but any rainfall we get will be much-needed rainfall. Anything we get to fill up the reservoirs is good news.”

The North Bay valleys could see anywhere from one to two inches of rain, with the North Bay mountains and coastal mountains expected to get two to four inches. Everywhere else in the Bay Area could receive 0.25 to 0.75 of an inch of rain.

California is still grappling with a severe drought after two dry winters in a row. The Oct. 24 storm also quelled widespread wildfire concerns in the region.

“The rainfall that we had in October has really, really improved conditions when it comes to fire concerns,” Mehle said. “The threat of having a widespread wildfire is not very likely at this time.”

It’s expected to be “breezy” on Monday and Tuesday but winds won’t be as “damaging” as the Oct. storm system, according to Mehle. Gusts could range from five to 15 mph on Monday night and Tuesday and coastal areas and mountains could get 30 to 40 mph winds.

Temperatures will be “seasonably cool” the next few days, with Friday and Saturday seeing temperatures in the 60s and 70s. Monday will be cooler “across the board,” with temperatures mainly in the 60s and Tuesday will be in the upper 50s to 60s.
