Heavy rain will soak portions of Washington and British Columbia through Friday, leading to flash flooding before spreading inland through the weekend.
“A fire hose of moisture extending from the western Pacific Ocean to western North America will focus over British Columbia to Washington state through Saturday,” AccuWeather Senior Meteorologist Brett Anderson.
The heaviest rain will fall across the Olympic and Cascade mountains of Washington as well as Vancouver Island and the Coastal Mountains of British Columbia. Total rainfall could exceed 10 inches (250 mm) in some locations through this weekend.
