A "strong atmospheric river" could bring more rain and mountain snow to the Northwest, according to forecasters.

“The main rain band is still in the North Bay (Wednesday) morning,” NWS meteorologist Brayden Murdock said. “But the winds are building up before the rains do. You’re starting to see some of the stronger ones moving to the south, and the rain will follow.”

Hydro Heroes, a Southwest Washington disaster cleanup and restoration company, has released comprehensive guidance on protecting residential foundations from water damage as the region prepares for its first atmospheric river system of the fall season.

In a Saturday forecast chart, the NWS noted that portions of Washington, Oregon, Idaho, and Montana will continue to experience an atmospheric river event, expected to continue throughout the day, tapering off on Sunday.
