Tornado in KANKAKEE, ILLINOIS

Location: SUN RIVER TERRACE
Tornado F-scale: EF1
Property damage: 0.00K

This tornado began just west of 8000 East Road at 2500 North Road west of Momence, based upon drone imagery provided by the Kankakee County Emergency Management Agency. The tornado produced EF-0 damage to a farm near the aforementioned intersection with damage to tree branches and part of a metal outbuilding roof damaged. The tornado continued east just south of 2500 North Road with a narrow, convergent path evident in a corn field from drone imagery. The tornado's intensity briefly weakened in the immediate vicinity of the Kankakee River with only limited tree damage noted. Just east of River South Road, the tornado again intensified as it moved through fields toward IL-17. Drone footage again indicated a narrow path of convergent damage in corn fields until the tornado moved into the backyards of a few residences on River South Road, causing significant damage to multiple trees. As the tornado moved east, drone footage revealed additional corn flattened in the field southwest of the Van Drunen Farms building. The tornado then struck a row of two-story apartment homes on Harvard Street, removing the roof and a portion of the upper-level walls from one of them and depositing the debris over the next couple of blocks to the east. Damage to the adjacent apartment homes was very minor. East of Harvard Street, there was little to no additional structural damage, but there was considerable damage to trees and power lines, especially along Indiana Street. East of Momence, the tornado continued along Route 114. Just west of N 13250E Road, it removed part of the roof of a metal outbuilding while snapping and uprooting additional trees. Little to no additional tornado damage was observed east of the intersection of Route 114 and N 13250E Road.
