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

An EF1 tornado formed southwest of Spring Valley and moved almost due north before dissipating west of Spring Valley. The tornado blew down a barn and damaged several other farm buildings along its path. Several new power poles along County Highway 1 were leaning after the storm.

The wider storm

Two rounds of severe storms moved across southeast Minnesota on April 12th. The first round occurred in the afternoon as storms producing large hail moved across the area. Quarter sized hail fell from north of Racine (Mower County) east to near Winona (Winona County). A second round of severe storms occurred in the evening. An EF2 tornado moved through Taopi (Mower County), where homes were destroyed or severely damaged, grain bins were destroyed, cars were tossed or rolled, and trees and power lines were downed. Two people sustained injuries while sheltering from the storm when they became trapped under debris. An EF1 tornado occurred just southwest of Spring Valley (Fillmore County), damaging several farm outbuildings and trees. Two EF0 tornadoes occurred southwest of Lewiston (Winona County), where the damage was mainly to trees and one farm. The Mower County Board of Commissioners ratified an emergency declaration for Taopi and a state of emergency was declared for Fillmore County.
