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.

What the National Weather Service wrote

An F1 tornado touched down in Elkland township about two miles northwest of Lincoln Falls on route 154, then moved northeast through a crossroads near Eldredsville to Hugo corners. Trees were blown down as the storm crossed route 154. Just west of McCarty Ridge Road a group of campers narrowly missed injury when a stand of trees were blown over near their site. The heaviest damage was along McCarty Ridge Road near the town of Eldredsville. A well built older home was lifted just slightly on its foundation. The occupants told of seeing a cloud of dust appear as they watched from their basement. A barn nearby was leveled. The roof flew off a sawmill and landed largely intact about 100 feet northwest of the mill. Several other homes had some structural damage and one had shingles removed from a roof. A travel trailer was overturned and an outdoor shed was destroyed. A couple mobile homes were damaged by debris, but were not moved off their foundations. Tree damage was sporadic along the path with a number of trees down in the Hugo Corners area near the end of the path.

Began near Hugos Corners (41.5200, -76.6700).
