The National Weather Service in Mount Holly NJ has confirmed a
tornado near Shartlesville in Berks County Pennsylvania on June
19, 2017.

A storm survey found a damage path of trees that were located on
private property behind Mountain Springs Campground on the
southern slope of Blue Mountain. The most concentrated damage
consisted of several large hardwood trees that were uprooted and
snapped at a private residence off of nearby Mountain Road. The
direction of the felled trees exhibited a rotational pattern
consistent with tornadic damage.

Geo-located damage photos from a trained storm spotter was used to
help estimate the beginning location of the tornado since the
NWS storm surveyor were unable to access the property. The
trained spotter observed tree damage just north of Interstate 78
adjacent near Campsite Road, Northkill Road and Forge Dam Road.

Additional video evidence of the tornado that was posted
on the Mount Holly, NJ Facebook page help confirm the tornado and
the general storm motion.

The National Weather Service would like to thank Lou Ruh, Skywarn
Coordinator, for his assistance in this storm survey.
