Flood — Jan 6, 2022

The second in a series of strong Pacific fronts brought another round of heavy rain and resulting flooding of mainstem rivers draining the coastal mountains and interior of northwest Oregon. Coastal flooding also occurred at some coastal communities as a result of high astronomical tides combined with high river levels and high seas.

Flood — Jan 3, 2021

A strong westerly upper level jet over the northern Pacific was directed at the Washington and Oregon coast, driving a plume of deep moisture toward western Washington and northwest Oregon.

Flood — Jan 16, 2011

A series of weather disturbances over the weekend brought sub-tropical moisture to the Pacific Northwest producing heavy rainfall over the region. The heavy rainfall combined with snowmelt runoff led to flooding on several rivers and streams in Northwest Oregon as well as landslides and debris flows.

Flood — Jan 8, 2009

A powerful storm system brought very heavy rainfall to the region in early January. The heavy rainfall combined with snowmelt runoff caused flooding along multiple rivers in southwest Washington.
