The path drawn at its surveyed width of 75 yards (0.04 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

A brief EF-0 tornado was analyzed in satellite imagery by the Northern Tornadoes Project of Canada. Damage was limited to trees on Neebish Island.

The wider storm

A seasonably strong shortwave rotated over the Great Lakes to produce a second round of severe thunderstorms across all of northern Michigan during the afternoon and evening of 8/11. The strongest storms tracked over and east of Kinross, MI and over the M-32 corridor from the Gaylord area into Alpena.

Began near Munnscong (46.2383, -84.1641).
