Tornado in SOMERSET, NEW JERSEY
From 26-JUN-23 14:29:00 to 26-JUN-23 14:34:00 (EST-5)
Location: BERNARDSVILLE
Tornado F-scale: EF1
Property damage: 0.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

An EF-1 tornado began in northern Somerset County near Bernardsville along the NJ Transit Line just to the southwest of the intersection of Minebrook Rd and Old Quarry Rd. There it dropped numerous trees onto the NJ Transit Line and snapped the trunk
of around ten trees. As it moved to the northeast, the storm uprooted two maple trees along Mine Brook behind the Rose Bowl Baseball field that were on a slight embankment. The storm continued to move towards the northeast into Bernardsville
where it produced tree damage along Laurel Lane and snapped the trunk of a tree that appeared not to be fully healthy. The tornado then started to move more towards the north following Mine Brook through Bernardsville producing damage from Timber
Rock Trail to Anderson Hill Rd where it snapped the trunk of a pine tree that ended up falling on a vehicle. The peak width of the tornado was over this area where the damage path was approximately Four hundred seventy five yards between the damage from Timber Rock Trail to Anderson Hill Rd. Additional damage was found along the path of Anderson Hill Rd moving to the north towards the intersection of Seney Dr and Anderson Hill Rd where numerous trees were brought down with at least two ending up on power lines. At the intersection of Anderson Hill Rd and Rolling Hill Rd, another
large tree had its trunk snapped. However, the interior of the tree was determined not to be healthy, so the expected winds based on the DoD were reduced significantly. As the storm was starting to occlude and weaken, it took down several more trees along
Old Fort Road including uprooting multiple trees with wide, but shallow root systems. The tornado then dissipated as the storm moved further to the northeast. The EF-1 rating is primarily based on the number of trees with snapped trunks with the highest
concentration in a single location being along the NJ transit line. This is where the damage indicator of hardwood trees with degree of damage of trunks snapped produced an expected wind speed of one hundred five mph.
