EF2 Tornado West of Aurora June 17

A tornado occurred west of Aurora, Nebraska on Wednesday evening, June 17th. The tornado touched down at the intersection of Highway 34 and Road G, and tracked east along U.S. Highway 34 for five miles, and lifted at Highway 34 and Road M.   The tornado lifted about 3 miles west of Aurora.   National Weather Service assessment teams surveyed the damage and rated the tornado an EF2, with winds between 111 and 135 mph.  A description of the EF scale can be found here.

The tornado struck a farm house 4 miles west of Aurora, causing the most damage (EF2).  The roof of the house was removed, and walls collapsed.  Outbuildings were destroyed and crops, trees and power poles were damaged.  About a dozen railroad train cars were overturned northeast of the farmstead.  Damage to the Iams plant was not associated with the tornado, as the tornado tracked one quarter mile south of the plant.  Strong inflow thunderstorm winds did cause roof and wall material to be blown off on parts of the Iams plant.  The ethanol plant did not sustain damage as the tornado tracked north and west of the ethanol plant.       

The tornado was on the ground for about 18 minutes, or from 8:59 pm to 9:17 pm local time. Photographs and video from storm spotters and storm chasers indicate the tornado was likely at least one-quarter mile wide at some point.  There were no injuries associated with the tornado.
