Late-May 1998 tornado outbreak and derecho – DOW recorded maximum wind speeds at 264 mph (425 km/h) at 160 ft (49 m) above ground level, which the NWS classified at almost ground level. Such wind speeds would fall well into the EF5 range on the Enhanced Fujita Scale, though the maximum damage intensity observed in the town of Spencer was F4.
The tornado cut a 14-mile path that was 500 yards wide, with wind speeds estimated at 100 miles per hour. Many trees and power poles were snapped in its path, and a barn was completely destroyed a ...
