New storm heading to Bay Area expected to soak entire region

More rain is on the way to Bay Area. It's expected to arrive Monday and linger into Tuesday, says meteorologist Mike Nicco.

SAN FRANCISCO (KGO) -- The Bay Area is getting ready for another soaking next week after three storms, including a record-setting atmospheric river drenched the region this week.

"Our next Bay Area-wide storm comes in Monday and it lingers through Tuesday," said ABC7 News meteorologist Mike Nicco.

The storm is a level 1 on our Storm Impact Scale.

"Light to moderate rain, becoming breezy, and we will probably need to upgrade this one to a 2 on our Storm Impact Scale due to the rainfall amounts that it's going to bring," explained Nicco.

Nicco's AccuWeather forecast shows Monday's storm will arrive in the North Bay first.

Santa Rosa will start getting wet around 5 a.m.

From there the storm will continue to move from north to south across our neighborhoods, according to Nicco.

"By the time we wake up Tuesday morning, we will have some left over light rain and then a few scattered showers. As we head throughout the day, the clouds will start to open up and this system will be over," said Nicco.

The new storm is welcome news to the Bay Area after a series of storms brought "very impressive" and much-needed rain to the region, but Nicco says we still have a long way to go.

The atmospheric river alone increased Livermore's rain percentage for January from 24% to 93%. Livermore also set a one-day record after getting more than an inch of rain on Thursday.

San Jose and Santa Rosa also experienced a day of record rainfall on Thursday.

The atmospheric river drenched Oakland with rain percentage for January increasing to 58%.

San Francisco went from 21% to 58%.

SFO went from 22% to 74%.

San Jose went from 15% to 92%.

Santa Rosa went from 26% to 59%.
