The path drawn at its surveyed width of 25 yards (0.01 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

NWS storm damage survey revealed a broken path of small to medium limbs down and several locations of small groups of trees uprooted indicating winds of 55 to 70 mph. The worst damage was found near Fillmore St between 108th and 104th Ave indicating winds of 75 to 85 mph. One outbuilding had a garage door blown in which caused a small section of roof to lift off. Trees on and near the property were uprooted and outdoor furniture was thrown toward the north across the property. There was some evidence of lofting as some debris was stuck in trees. A camper trailer was flipped over northeast of that location but a nearby turkey barn did not appear to be damaged. A few trees were down just south of Ottawa Area Center school near the end of

the path.

The wider storm

A low pressure system and warm front combined to setup conditions favorable for the development of several weak tornadoes on June 26th. Storm damage surveys were conducted and it was determined that two EF-1 tornadoes occurred and that several EF-0 tornadoes occurred.

Began near Olive Center (42.9329, -86.0620).
