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

"The only clothes I got is just my pajamas," 7-year-old Jocelyn Rosas told CBS News' Carter Evans, as flooding devastated parts of Washington state.

An atmospheric river, whose moisture spanned a remarkable 7,000 miles across the Pacific from the Philippines to the Pacific Northwest, caused record river levels and destructive flooding across Washington state this week.

Gov. Bob Ferguson, who has warned that as many as 100,000 people would need to evacuate statewide, said Friday the Trump administration has approved a disaster declaration.

Record flooding in Washington state has forced tens of thousands of people to evacuate after torrential rains this week.

Washington is prone to intense spells of fall rainfall, but these storms have been exceptional, and more rain is on the way this weekend.

Portions of western Washington state have experienced a month’s worth of rain within the past few days, causing historic flooding, damaging mudslides and more than 100,00 people facing potential evacuations.
