A wind trace from the Whiskey Run Turbine Site, about 12 miles south of Coos Bay in Oregon, showed peak gusts to 97 mph fifty feet above ground level. The wind caused widespread damage in Washington and Oregon, with 12 deaths reported. As much as four feet of snow fell in the Sierra Nevada Range of northern California.
