The path drawn at its surveyed width of 30 yards (0.02 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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

A tornado touched down about 8 miles west-northwest of Williams in the Junipine Estates neighborhood. Ten 10 structures were damaged and or destroyed (homes and outbuildings). One power poll was blown down and the power was out in the entire community. Camping trailers/mobile homes were turn over. Some rooves were blown off houses.

The wider storm

A large area of low pressure was stationed over eastern Montana with shortwaves rotating around it over northern Arizona. This provided dynamic support to an already moist

environment with numerous showers and thunderstorms. A stronger shortwave moved from the northwest to southcentral portions of Arizona during the afternoon to provide even more lift to an already unstable atmosphere. Some storms became severe with hail and at least one tornado.

Began near Perrin (35.3600, -112.2108).
