Tornado in NORFOLK, MASSACHUSETTS
From 29-JUL-23 19:17:00 to 29-JUL-23 19:18:00 (EST-5)
Location: EAST FOXBORO
Tornado F-scale: EF0
Property damage: 5.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

Tornado confirmed to have touched down in a small neighborhood in
Foxboro near the Mansfield town line very close to the town of Easton.
Several locations on a west to east path in the neighborhood had several
large trees up to 2 feet in diameter snapped at the trunk.
Observed tree damage had a convergent pattern consistent with
violently rotating winds. No major damage to homes was observed,
but one chimney appeared to have been knocked over by a fallen
tree. Path width was estimated to be around 25 yards. Path length
of the surveyed damage points was just shy of 300 yards. Per
radar data, a velocity couplet was over the surveyed neighborhood
for only a minute or two before continuing east over conservation
land. It is possible that the tornado was on the ground for
longer, but surveyors were unable to access conservation land
east of the last surveyed damage point. Additional significant
tree damage was found east of aforementioned conservation land in Easton,
but patterns were more consistent with west to east straight line winds.
This is also consistent with archived KBOX radar which displayed strong
outbound (west to east) velocities over this area.
