Mike Ginter helps collect pieces of his father’, barn after a tornado-like wind tore the roof off, sending peices approximately 600 feet away and in to a field in Hockinson on Thursday. A small tornado tore through a barn in Hockinson on Thursday afternoon as dark skies, hail and heavy rain swept through Clark County. Irene Ginter was going to get a glass of water just after 4 p.m. at her home off Northeast 189th Street when she heard a loud crack. Looking out the kitchen window, she saw a rotating funnel touch down on top of the barn. Within 10-15 seconds, the funnel took most of the corrugated metal roof and half of the wooden barn with it.“I looked out the window and there was this twirl, something rotating … and the roof was just flying all over the place,” she said. “I’m still kind of in shock.”Mike Ginter was parking a tractor in his barn, south of his parents’ home, when he saw the roof fly up about 50 feet into the air and toss debris across the field to the southeast and northeast. “I was wondering, ‘Where’s Dorothy?’ ” he said. Nine black Angus cattle, spooked by the weather, ran south of the barn toward a wooded area. Preliminary reports from the National Weather Service in Portland classified the tornado’s strength as an EF0 on the Fujita scale, with winds estimated at 60 to 85 mph. Fire District 3 was dispatched to the home at 4:14 p.m. It assessed the structure and assisted the family in salvaging the contents of the barn spread out over a 10-acre area, said Deputy Chief Scott Sorenson.
