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

For the Dane County portion of this tornado, it was mainly at EF-1 intensity and entered the county just to the northwest of Edgerton and exited on the northwest side of Lake Koshkonong. It went through the far south side of Albion and appeared to cross Interstate 39 just north of the Highway 73 exit.

The wider storm

A historic tornado event for Wisconsin as the first documented tornado occurred in the month of February. An approaching cold front and upper level disturbance initiated the severe thunderstorms from late afternoon into the early evening. An EF-1 tornado occurred in Green County near Juda/Albany and then a second tornado developed which was stronger and produced EF-2 level damage. The long track tornado impacted 30 houses and numerous barns and outbuildings. Only 1 injury occurred when the tornado hit someone driving a car near Hwy 14 and Territorial Rd. A high volume of hail also occurred with these storms, but the largest hailstone were generally just at or above severe levels.

Began near Hanerville (42.8471, -89.1193).
