 Brief Description: EVENT NARRATIVE: On December 14th at 11:40 AM PST, a tornado with an Enhanced Fujita Scale rating of EF2 moved northeast across the community of Aumsville, Oregon. The estimated length of the tornado path was 5 miles with a width of 150 yards. There were two minor injuries, fifty structures damaged, more than thirty large trees blown down or snapped off, five sheds damaged and two semi-trailers tipped over. The estimated value of the damage was $1.2 million. EPISODE NARRATIVE: A strong cold pool of air aloft produced a very unstable airmass over western Oregon. A vigorous low pressure center was just off the Washington Coast with a surface trough moving through western Oregon. This trough served as a focus for thunderstorms during the day. One of these thunderstorms produced a tornado that wreaked havoc on the community of Aumsville.
