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 weak EF0 tornado with peak winds near 80 mph briefly touched down in Ponte Vedra Beach near Guana River State Park. The tornado caused tree damage and some structural damage to nearby homes including a broken window. A tree was blown down near Sea Hammock Way.

The wider storm

A pre-frontal line of strong to severe storms moved across NE FL and SE GA during the afternoon and pressed offshore of the Atlantic coast into the evening. Surface based CAPEs rose up to 1000 J/kg over parts of the Suwannee Valley and inland SE GA. This instability shifted east across the remainder of NE FL into the evening coinciding with elevated moisture and dynamics that produced a few severe storms and also 2 confirmed tornadoes.

Began near Palm Vly (30.1407, -81.3564).
