Pacific Northwest Faces Flooding Risk as Atmospheric Rivers Continue

Over 10 Million People Under Flood Watches, with Heavy Rainfall Expected to Continue Through Wednesday

An ongoing atmospheric river event is causing heavy rainfall, snow, and potential flooding across the Pacific Northwest, with over 10 million people under flood watches.
Washington’s Olympic mountains could receive as much as 10 inches of rain, and the Cascades could see between 5 to 9 inches.
The sequence of back-to-back atmospheric rivers, called an AR family, began Saturday and will continue across this region through Wednesday without much of a break period in between systems.
Parts of Utah and Colorado received snowfall on Monday, bringing total snowfall throughout the atmospheric river events to several feet in some places.
Portland, Oregon; Eugene, Oregon; Seattle, Washington, and several other areas were at risk for up to 12 inches of rain through Sunday.
