KOIN 6 News and Portland's CW dives deeper into the fall leaves and rain threat to drivers around the Pacific Northwest as an atmospheric river ramps up this week.

Cabot and Danville received about 2.5 inches of rain Wednesday afternoon, according to the National Weather Service. A potential for localized flash flooding continued into the evening.
