A series of three consecutive storm systems will move through the Bay Area over the weekend, drenching the region with amounts of rain that could lead to minor risks of flooding and mudslides in some areas.
The first system is expected to make landfall Friday night across most of the Bay Area, followed closely by the second storm throughout the day and night Saturday, according to the National Weather Service.
Then, after a lull from Saturday night into Sunday morning, the third system is expected to arrive in a strong jet stream from the Pacific Ocean and will likely produce moderate to heavy rain and gusty winds from the Pacific. southwest from Sunday afternoon to early Monday.
It could also produce thunderstorms on the Peninsula, in the North Bay and in Santa Cruz, Monterey and San Benito counties.
“The first and second systems are expected to dump up to an inch (of rain) on the city and then the third could dump up to an inch and a half on the city,” National Weather Service meteorologist Roger Gass said.
“The North Bay Mountains, of course, will see the heaviest rainfall – up to about 7 and a half inches from all three storms combined,” Gass added.
While the storms contain some subtropical moisture, they are not considered a classic atmospheric river, which typically moves more slowly through the region and then stops.
The repeated rainfall expected in the coming days will fall on already saturated soils, which could cause landslides and downed trees and power lines.
In addition, according to the weather service, people should be prepared for rapid flooding of rivers and streams, as well as small “nuisance” floods throughout the region.
