Event narrative

Devastating Ice Storm in the Columbia River Gorge, with ice accumulations generally around 1 to 2 inches. Interstate 84 (I-84) through the Gorge was closed for a good part of 3 days.

Wider weather episode

An approaching low pressure system brought rain across the Columbia River Gorge, while cold air was trapped at the surface and was slow to clear out. This brought a tremendous amount of freezing rain to the Columbia Gorge, closing I-84 and SR-14 to travel through the Gorge. Freezing rain was observed as far west as the Portland Airport, impacting the east side of the Portland Metro as well.
