The wider storm

A series of slow moving fronts brought periods of heavy rain along with strong winds. This resulted in high surf; coastal, river and urban flooding; landslides; and debris flows. As the front moved inland early on the 13th, a debris flow resulted in a fatality in the Columbia River Gorge. The front brought a burst of 35-50 mph winds to the Willamette Valley and southwest Washington interior resulting in over 100K customers without power across southwest Washington and northwest Oregon.
