An EF-4 monster wedge tornado snaked its way between several of our Iowa communities last Friday around dusk. With a damage path that stretched 25 miles long, the twister claimed several farmsteads and threw farm equipment like toys. Near the town of Pierson, this grain wagon was found 400 yards away!
The National Weather Service assessment team estimated these peak winds at 170 mph, claiming the EF-4 mark. That falls within the enhanced range of 166-200 mph. The tornado was on the ground for roughly 42 minutes, finally ending near Washta at 7:17 p.m. It carved out a path up to one and a half miles wide, while decimating shed and damaging many homes.
The tornado's signature hook echo passed through Woodbury and Plymouth counties. Both of these form the southern border of the KELOLAND coverage area.
