A tornado formed in southeastern Pennsylvania Monday and an EFO tornado may have grazed Delaware, according to the National Weather Service.
The NWS said Tuesday the severe storms that walloped muched of the Northeast spawned a tornado near Shartlesville in Berks County, Pennsylvania. A survey of the southern slope of Blue Mountain conducted after the storm found damage consistent with "tornadic damage," the NWS said.
"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 agency said. "The direction of the fallen trees exhibited a rotational pattern consistent with tornadic damage."
Several videos posted online showed what appeared to be funnel clouds near Shartlesville, about 75 miles northwest of Philadelphia. The NWS said the videos provided additional evidence of the tornado.
Meanwhile, an initial assessment of damage near Greeenwood, Delaware, appears to signal an EFO tornado. The NWS says the tornadic damage embedded in the larger straight line wind damage near Greenwood, Delaware. The initial assessment is that the tornado was an EF0.
Surveillance video from outside a warehouse under construction in Greenwood, Delaware, showed a sudden burst of wind and rain around 6:30 p.m. Debris from the site, located along Sussex Highway and owned by the Delaware Electric Co-Op, could be seen tossed around. The warehouse's roof and several trees were damaged.
Jeremy Tucker, spokesman for the electric company, said had the storm hit an hour earlier, construction workers could have been injured by the flying debris.
Several videos also surfaced showing what appeared to be a funnel cloud near Shartlesville, Berks County. It’s unclear from the videos however whether or not it touched down.
During the storms, tornado warnings were issued in the area immediately west of Berks County, Pennsylvania, and Sussex County and the lower edge of Kent County in Delaware.
