A tornado developed within Laurel Hill State Park during the afternoon hours
of Thursday, July 29, 2021. Somerset County Emergency Management conducted a
thorough damage survey, consisting of photos from the ground along with photos
and videos from a drone. The tornado began just north of Laurel Hill Park
Drive and continued on a southeast track through a portion of the park containing
several conservation buildings. Numerous trees were uprooted in various directions,
while a few were also snapped, resulting in damage to some of the conservation buildings.
Estimated maximum winds reached 102 mph as the tornado tracked through this portion of the
park, before turning to the east and producing additional tree damage east of Laurel Hill
Park Drive. Additionally, several videos of the tornado were sent in to the NWS from media
partners and storm spotters. Farther west on Laurel Hill Park road, near the intersection
with Buck Run Road, scattered unidirectional wind damage was found in association with the
rear flank downdraft of the tornado.
