BURLINGTON — Floodwaters began to recede on Friday after historic inundation in Washington state, but the areas hardest hit by flooding could face another wave of atmospheric river next week, and more inundation is looming.

The moisture from this storm system will help two fast-moving winter storms spread snow across the eastern U.S., with another atmospheric river on its way.

There are already at least four rivers in Washington at major flood stage.

A rushing river claimed a bridge in Libby, Montana after a powerful atmospheric river bought rounds of rain into the region.

More than 10 inches of rain has fallen in parts of Washington this week as a strong atmospheric river hits the state.

Authorities are going door-to-door in South Prairie, Washington, in Pierce County, urging residents to leave their homes immediately as water rises there. The Pierce County Sheriff’s Office previously said that at least 25 people have been rescued in the county since Wednesday, including in South Prairie.
