The path drawn at its surveyed width of 100 yards (0.06 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

An EF-0 tornado continued in Ramsey County, near Spring Lake, then north-northeast as it crossed back into Anoka County, near Highway 10, south of the Blaine-Anoka County Airport. Most of the damage was confined to sporadic trees blown down along the path.
