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

An EF1 tornado touched down around 1322 pm EST in Bradford County and continued for a brief period as an EF0 event in Clay County. The path width varied from 200 to 400 yards, and the total path length was around 10 miles. The storm was only present in a small portion of Clay County and entered the Camp Blanding National Guard Facility.

The wider storm

A strong storm system tracked across the deep south while the mid and upper level low moved over the Mississippi River Valley. A surface low developed over south Georgia in the afternoon, and a trailing squall line moved across the area in the afternoon and evening. Strong low level shear, including a 50 to 60 knot low level jet, combined with adequate instability to produce widespread severe storms across the area.

Began near Kingsley (30.0125, -82.0459).
