Days of relentless rain in Washington state have unleashed historic flooding that has stranded families, destroyed homes, and swept away bridges. With even worse flooding expected Friday, officials warn the situation could become catastrophic.

DC Fire and EMS were called to the 1400 block of Savannah St. after the basement of a 2-story apartment building flooded. The water came up to about 8 feet. Crews were using submersible pumps to help drain the water. Five residents were displaced as a result.

Flooding from a water main break has closed the Woodley Park Metro Station, causing train bypasses and delays.

Washington state residents are bracing for possible mudslides and levee failures from floodwaters that are expected to be slow to recede.

Drier weather is coming, but flooding effects are likely to continue for days across portions of western Washington state and northwestern Oregon.

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.

Gov. Bob Ferguson and other state officials cautioned that more rainfall was expected after rivers hit record flood levels across the region, while residents worried about the long-term future.
