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.

NOAA’s online database has no written narrative for tornadoes before 1996 — just the numbers above, transcribed from the original storm logs. Written accounts from this era do exist in NOAA’s monthly Storm Data publications (scanned, back to 1959).

Source: NOAA Storm Events Database, event 10357855. Narratives are written by the National Weather Service forecast office that issued the report.
