EF0 tornado in Tillamook County, Oregon

EF-0 tornado with estimated winds of 85 mph. The tornado briefly touched down in Rockaway Beach, OR. It occurred around 9:24 PM 11/11/24 and lasted one to two minutes or so according to the spotter that reported it. KRTX radar imagery depicted a fairly strong velocity couplet over Rockaway Beach. This likely formed as a waterspout then made landfall, though the path was not continuous. There were multiple reports of damage to fences, roof shingles, and a window and dirt/debris being tossed around. Upon further investigation, more security camera video footage was received from the Neah-Kah-Nie School district showing distinct rotation of a tornado moving through a parking lot where several items were thrown or moved including portions of a baseball dug-out, porta-potty, and several dumpsters. A garage on the premises had its roof blown off and the garage doors blown in. One minor injury was reported. The maximum width of the the tornado is estimated at 150 yards and an estimated path length of 0.25 miles based on damage reports.

Convective and unstable post-frontal environment saw shower and isolated thunderstorm activity enhance on the evening of Nov 11th as the axis of the upper-trough shifted overhead. Enough instability and low-level shear was present to produce an isolated tornado.
