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

A brief, narrow tornado embedded in intense downburst winds struck a portion of Martell, NE. The tornado uprooted and snapped trees, caused roof and siding damage, and tore the roof off a BnB that was attached to a large barn. The tornado's width was only 100 yards wide and a little more than a quarter mile long.

The wider storm

A line of storms developed in central Nebraska where they merged and began to bow as it approached southeast Nebraska. The surging storms produced widespread wind damage downing trees, powerlines, and removed the roof from a hog barn. The strongest measured wind gust was 81 mph near Dorchester in Saline County.

Began near Martell (40.6358, -96.7625).
