Comments | Based on the ground based storm survey and available photographs, the tornado appeared to begin just south of Otter Creek on 150th Ave where a grain bin was displaced across the road along with scattered tree damage. The tornado continued east/southeast across agricultural land producing scattered tree damage in shelter belts until crossing US Highway 65. The most significant occurred just east of US 65 as the tornado produced significant damage to the Iowa Operator Engineers Training Facility. Several metal building systems were nearly completely destroyed, including the complete separation of metal floor footing from concrete. Debris from this damage was spread over 1/4 mile into surrounding fields. Based on this evidence, the EF-scale rating has been determined to be EF3, with peak winds near 150 mph. The tornado continued eastward producing minor to moderate roof and siding damage to several farmsteads and outbuildings along and north of Roosevelt Street. Additional tree damage was noted eastward to 190th Ave before the damage become more inconclusive due to lack of road access. Additional modifications to this track may be made pending final review of drone footage.
