The path drawn at its surveyed width of 33 yards (0.02 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

A NWS storm survey confirmed a short and narrow damage path about 0.25 miles long and 100 feet wide. Eyewitnesses reported seeing a funnel cloud before residences were damaged. The damage path started near the corner of Puma and Chinchilla Streets. The damage path extended northeast to near the corner of Bear Street and Cougar Drive. Approximately 10 homes received minor damage. The most extensive damage was one carport being destroyed and also causing shingle and roof cap damage. Winds were estimated at 70 mph.
