The path drawn at its surveyed width of 100 yards (0.06 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

Around 330 pm a tornado touched down near Bradshaw Road where it damaged trees. The tornado tracked north-northeast and continued to snap trees as it tracked across SW Bellmont Drive and damage a small barn as it nearly paralleled State Road 47. The tornado path then tracked NNE along SW State Road 47 where it damaged large oak trees and power lines. The tornado peaked in intensity in this area with max winds around 85 mph. The tornado lifted just east of the State Road 47 along SW Wester Drive.

The wider storm

Deep tropical moisture was in place (PWAT 2.5) with the area on the east side of TS

Cristobal as the storm approached the LA Gulf Coast. Waves of moderate to heavy rainfall with isolated embedded thunderstorms pivoted northward across the local forecast area into the evening with a more solid band of moderate to heavy rainfall developing across north Florida as low level convergence increased between a lifting frontal zones across south-central FL and a persistent low level ridge axis holding firm just north of the Altamaha River basin. This ridge will limit the northward extend/expansion of the convective band into Sun, and generally focused a W-E oriented swath of heavy rainfall generally near and south of the I-10 corridor overnight into Sunday morning on 6/7. The ridge strengthened north of the Altamaha Region Sun afternoon 6/7, which shunt the corridor of heavy rain SSW toward the I-75 corridor of NE FL with drier mid level air (700-500 mb) decreasing rain chances across SE GA and eastern NE FL into Sun evening. In addition to heavy rainfall potential, there was a low tornado threat for NE FL into the evening of 6/6 with elevated 0-1 km shear values 20-25 kts with low level ESE winds under increasing SSW winds out of the GOMEX, with speeds increasing to 35-45 kts at 850 mb through 06z Sun 6/7.

Began near Bass (30.0870, -82.6754).
