Survey Summary:
The National Weather Service confirms that a tornado occurred in
Elk County at approximately 2:51 pm on May 4, 2021. Photo
evidence shows tree damage concentrated along a narrow area along
Old Byrnedale Rd and Route 255 about 2.5 miles NNW of Weedville,
PA. Several trees were uprooted or snapped. This is likely near
the end of the damage path, based on weakening low level rotation
and updraft strength observed by radar. Video evidence from
Weedville shows a rapidly rotating funnel approximately 0.5 miles
WSW of Route 255. A ridge line obstructed the view of the ground
beneath the funnel. However, a radar-indicated tornado debris
signature supports the idea that the tornado was likely on the
ground and lofting debris at the time. The path start and end
points, path width, and tornado strength are preliminary
estimates and will be adjusted as necessary if new evidence of
damage is found.
