This Date in Weather History

1981 - A powerful cyclone brought high winds to Washington State and Oregon. The cyclone, which formed about 1000 miles west of San Francisco, intensified rapidly as it approached the Oregon coast with the central pressure reaching 28.22 inches. 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.
