The path drawn at its surveyed width of 80 yards (0.05 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

This tornado was reported by local law enforcement with portions of it also captured on video. Some of the path was also evident in high resolution satellite imagery. This tornado remained mostly in open cropland doing damage to corn and beans. However, it did pass by a couple of farmsteads with EF0 damage to trees.

The wider storm

A derecho swept across South Dakota and into Iowa on the evening of July 5th. This resulted in a swath of wind gust from 50 to 65 plus mph resulting in a number of power outages, tree damage, and a few damaged structures. A brief tornado occurred near Estherville with minor damage. As the bowing thunderstorm complex reach central Iowa the gusts had dropped below severe criteria given the less favorable environment with decreased deep layer shear.

Began near Estherville (43.4147, -94.8919).
