The path drawn at its surveyed width of 25 yards (0.01 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 second tornado has been confirmed by public video northeast of where

the Addison tornado occurred at 6:50 PM EDT. Video shows damage to

softwood trees. Locations are estimated from video and radar.

The wider storm

A unseasonably strong mid-level disturbance (shortwave) moved across a weakly unstable airmass during the evening of July 18th. Scattered showers and a temporary embedded thunderstorm or two developed behind the main rain shield and moved across VT. This particular cell had no history of thunder but enough of an updraft tapped the strong mid-level wind field above to produce a weak EF-1 tornado that lasted only a few minutes at most.

Began near Vergennes (44.1319, -73.2723).
