Des Moines, Iowa – The National Weather Service has confirmed a trio of small tornadoes touched down in eastern and central Iowa on Monday.
The National Weather Service indicates three tornadoes — each about 10-yards wide and rated an EF-0 with maximum wind speeds estimated between 70 and 75 miles per hour — touched down briefly in Butler, Grundy and Hardin counties. Survey teams assessed the damage in those areas on Tuesday.
In Butler County, they determined a small twister was on the ground for about two minutes and caused some minor damage in a 1.6-mile-long path east of Parkersburg. To the south, in Grundy County, a tornado was on the ground for about one minute, but caused no structural damage in a path covering about two-tenths-of-a-mile just west of Grundy Center. Further west, in Hardin County, a twister that knocked down trees and power lines and overturned a vehicle in Radcliffe, was on the ground about four minutes and left a path of destruction estimated to be a mile long.
At least six tornadoes were reported across Iowa on Monday.
