Today is the 50th anniversary of the 1962 Columbus Day Storm, which was produced by the most powerful extratropical cyclone to affect the west coast of the United States during the instrumented record. It was an unbelievable event, and there hasn't been anything like it since.
The cyclone could be traced to Typhoon Freda in the western tropical Pacific. Freda underwent extratropical transition, migrated across the Pacific, and then intensified off the Oregon coast, attaining of minimum central pressure of 955 mb. Analyses from Lynott and Cramer (1966) show the structure of the storm as it rumbled up the Pacific Northwest coast.
