The path drawn at its surveyed width of 50 yards (0.03 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

The tornado started on Boones Ferry Rd NE, west of the Aurora airport. Greenhouses in the area sustained damage, and the tornado continued to travel east across the airport property. Two planes were flipped at Willamette Aviation Services. The tornado ended near Airport Rd NE.

A somewhat weak low pressure system moving into Washington brought showers and thunderstorms across northwest Oregon. These storms had been showing weak rotation until one produced a tornado at the Aurora Airport.
