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 developed between Rudd and Rockford and moved east before dissipating northwest of Charles City. The roof of a home near Rockford sustained some damage. Near the end of the path, a hog confinement building was heavily damaged, trees were downed and windows blown out of a house. Otherwise, the damage was limited to crops.
