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

A very brief tornado touched down IL just east of Illinois Route 4 and just north of Lower Marine Road where it collapsed the overhead doors of a metal building and caused minor roof damage to a double wide manufactured home. The tornado lifted shortly after.

The wider storm

Multiple rounds of severe thunderstorms passed through the region for nearly the entirety of April 27th. The afternoon round was expected to be the most volatile, with an environment primed for high-end severe weather reflected by an areawide SPC Moderate Risk. What culminated was widespread large hail, wind damage, and three tornadoes in Illinois.

Began near Marine (38.7587, -89.8004).
