EF-0 TORNADO CONFIRMED, MULTNOMAH COUNTY, SEPT. 8, 2019

NWS confirms an EF-0 tornado Sunday for three minutes, 6:44-6:47 pm in western Multnomah County. Winds estimated at 65 mph, path length 800 feet by 360 feet wide at maximum. No injuries but minor damage reported at Plumpers Pumpkin Patch near Cornelius Pass Road.  

The weather service did not find any damage in Clark County and believes the funnel cloud either did not touch down or did so briefly in the Orchards area with no consequence. So for the record book, it looks like one not two Sunday tornadoes.  

An upper level low and disturbance along with 85 knot jet winds aloft and much calmer winds at 5,000 feet may have produced the rotation and wind speed shear to spawn the tornado.
