MOUNT VERNON, Washington: Tens of thousands of residents in western Washington could face evacuation orders when another round of heavy rain drops on the region Thursday,…

“Catastrophic flooding is likely” in many areas and the state is requesting water rescue teams and boats, Gov. Bob Ferguson (D) said.

An atmospheric river has caused torrential rain to parts of Canada and the United States.

“The flooding levels we’re looking at are potentially historic in nature, so we just want to emphasize how serious the situation is,” Gov. Bob Ferguson said.

Intense downpours were swept into the region this week by an 'atmospheric river' storm system from the Pacific Ocean.

Heavy rains drenching the Pacific Northwest triggered flooding on Thursday, closing dozens of roads and prompting evacuations of thousands of people.

Torrential rain has caused mudslides, washed out roads and submerged vehicles with more deluges expected on Sunday
