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

A tornado touched down in a corn field in Batavia and moved northeast. The tornado tore the roof off a home and destroyed the attached garage. The roof was carried about 0.25 mile. As the tornado crossed Route 5, it lifted a delivery van into the air and dropped it onto an oncoming tractor trailer. Both drivers were killed instantly. The tornado continued moving northeast, briefly lifting over a field. At its second touchdown, the tornado uprooted several trees in a circular fashion. It then uprooted several more large trees which fell onto a house. As scattered path of damage continued northeast where additional damage occurred to a house and barn. Telephone poles were also snapped along the damage path. (M41V) (M47V)
