Event narrative

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 Vancouver Airport, impacting the east side of the Vancouver Metro as well, mainly near the Columbia River.
