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 southern Seminole County just north of Aloma Avenue and moved northeast, crossing the 417 Beltway and lifting along West Chapman Road. The tornado severly damaged four homes. Eight homes had moderate damage and 32 homes and mobile homes had minor damage.

The wider storm

A small-scale area of low pressure, referred to as a mesolow, formed over the Gulf of Mexico along a cold front which was moving into central Florida. The center of this feature was accompanied by a small band of showers and lightning storms as it moved onshore near the mouth of Tampa Bay. These storms moved rapidly northeast at 35 to 40 mph crossing the Kissimmee River into northwestern Osceola County. With the mesolow increasing, significant rotation was noted on doppler radar as the storms moved through northwestern Orange County and then into Seminole County.

Began near Oviedo (28.6200, -81.2500).
