The National Weather Service in Valley, NE., says damage in Oakland during Tuesday evening’s storms was caused by an EF-2 Tornado. On Wednesday, a storm survey team looked at damage around Oakland. The results showed a large area of intense hail and wind damage across eastern Pottawattamie County.

Wind damage exceeded 100-miles per hour in some areas, with structures blown down, a roof torn off of a home, and sheds and barns flattened. A four-mile stretch of high tension power poles were bent and numerous trees were blown down. In addition, there were swaths of very large hail damage to homes and businesses. Within the second swath of wind and hail damage, a short-track tornado was detected.

The tornado’s start time has yet to be determined, but it formed slightly over 8-miles west-northwest of Oakland and traveled nearly six-miles to the west of Oakland before it diminished. At the onset, the E-F 2 twister with winds estimated at 115-miles per hour, downed numerous trees. It proceeded east-southeast and hit a farm house and destroyed a garage, a barn, and severely damaged several other sheds.

The tornado’s path was 2.9-miles long and 575 yards wide. An EF-2 tornado is considered “Strong.” It can pack winds from 111-to 135-miles per hour.
