The path drawn at its surveyed width of 25 yards (0.01 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 National Weather Service survey team confirmed an EF-0 tornado. The tornado started north of NE 31st Ave and NE 144th St and ended near the col-de-sac on NE 33rd Ave. Two large trees lost limbs, a couple fences were blown over, and some patio furniture were damaged; however, there was no structural damage to any houses in the neighborhood.

The wider storm

A low pressure system moving into Washington brought showers and thunderstorms across southwest Washington. These storms had been showing weak rotation. One of these storms produced a tornado near Vancouver.

Began near Salmon Creek (45.7259, -122.6393).
