California storm floods: Mapping the impact across Northern California

View as Map

The storms that have pummeled California since January are part of an atmospheric river event that has brought major flooding and damage to parts of Northern California. The National Weather Service issued flood warnings for much of the Bay Area.

Monday's storm is a slow-moving system in a string of atmospheric river events that have saturated the ground and pushed stream flows to historic limits.

Below, we've mapped the parts of the Bay Area hit hardest by the floods, starting back in January and continuing up until today. Curbed SF will continue to update this map throughout the storm.

"Smith, 69, is homeless and was sleeping in his car near the Corona Road overpass of Highway 101 when he woke up to find danger slopping toward his wheels from the surging Petaluma River."

January 10: While much of the South Bay was spared the damage seen up north, Highway 101 in Gilroy shut down in both directions on Sunday due to flooding. It reopened early Monday.

Yuba River, Sacramento

Copy Link
January 10: For the first time since 2006, the Sacramento Weir, a low-lying dam built across the river, was opened in order to prevent flooding of downtown Sacramento. "While the system’s five other weirs overflow automatically once the river reaches a certain elevation, the 1,920-foot-long Sacramento Weir consists of 48 gates that must be opened with a long hooked pole," reports Sacramento Bee. "The gates are opened when the river level at the I Street Bridge reaches 29.87 feet."

Sacramento River

January 10: "Rick Sorenson, owner of the Rio Ramaza Marina, wades in the Sacramento River as it begins to make its way up the levee on Garden Highway on Monday," reports Sacramento Bee. "He was securing an old paddlewheel boat on his property with the help of Ron Rudis." The floodgates of the Sacramento River were opened on Monday, which released water into the Yolo Bypass.
