What F1 means. This tornado was rated on Fujita’s original scale, used until 2007. F1 meant moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken; the scale paired it with winds of 73–112 mph, figures later judged too high, especially toward the top of the scale, and revised downward in the Enhanced Fujita scale. Ratings then, as now, came from the damage.

The wider storm

Thunderstorms developed along a strong cold front that moved through Wisconsin during the evening. Some of the storms produced hail to golf ball size and winds as high as 60 mph. The high winds downed trees and power line, knocking out power to about 3,100 customers, mainly around Wausau (Marathon co.).Two tornadoes developed from the storms. The first tornado briefly touched down about 5 miles west of Athens (Marathon co.) and caused minimal damage. The second tornado passed north of Wausau and stayed on the ground for about 5 miles, destroying two barns, a garage and a shed. It also snapped hundreds of trees, heavily damaged 6 homes and caused minor damage to 25 others. At least two vehicles traveling on Highway 51 were blown off the road. A trailer being towed by one of the vehicles was blown over and a large road sign hit the vehicle. The driver was injured and was transported to the hospital.

Began near Wausau (45.0333, -89.7167).
