The path drawn at its surveyed width of 250 yards (0.14 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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 embedded in a squall line which also produced large hail and a wide swath of damaging downburst winds. the most extreme tornado damage was observed at two farmsteads northwest of elliot and in the town of elliot where wooden quonset structures and large steel grain bins were violently crumpled and tossed in various directions. Peak winds estimated to 105 mph.
