Atmospheric river threatens to flood Northern California as state prepares for storms

The National Weather Service has issued a flood warning for part of Northern California as the state prepares for widespread rain later this week.

There is a risk of flooding in the northern Sacramento Valley near Redding, the Bay Area, the Sierra foothills and the Sacramento region south of Stockton.

One to four inches of rain are expected in the valley and more in the foothills.

Flood forecast published on Monday 29 January.

Surveillance is in effect from Wednesday to Friday morning for the Motherlode, southwest Shasta County, western Colusa County, the northeast foothills and the Sacramento Valley, according to the weather service.

“Excessive runoff can lead to flooding of rivers, creeks, creeks, and other low-lying, flood-prone locations,” the watch says.

A separate watch has been issued for the Bay Area and Central Coast.

Flood Watch issued for the Bay Area and Central Coast on Monday, January 29.

This comes as the region braces for another atmospheric river storm, which is expected to bring above-normal precipitation on the West Coast.

Courtney Carpenter, a meteorologist with the weather service, told the Sacramento Bee on Monday that residents can expect a weak to moderate system.

A flood watch is a step up from a flood warning. In a watch, you are asked to prepare. A warning is imminent.

“Water accumulation on roads, flooding on rivers and streams, and minor flooding in areas of poor drainage will all be possible,” the weather service said Monday.

A second storm system is expected this weekend, according to Daniel Swain, a climatologist at the University of California, Los Angeles, who could cause more flooding concerns in Southern California.
