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

The tornado touched down in northeastern Blue Earth County and moved east-southeast before tracking into Waseca County. While in Blue Earth County, it hit a couple sheds and also uprooted or broke several dozen trees. Several power poles were knocked down.

The wider storm

A nearly stationary front was draped across southern Minnesota on the afternoon of Monday, August 5, 2024. A very unstable airmass with strong shear was present along and south of the front. Two supercells developed over Nicollet and Watonwan Counties, then strengthened while tracking southeast. Supercells eventually formed a line of severe thunderstorms, which continued to result in occasional tornadoes and damaging wind gusts across south central MN.

Began near St Clair (44.1281, -93.8133).
