After striking Dry Tavern, the tornado passed near Smithfield (then also called Smithville) before lifting for some time. Debris from the storm fell in nearby Uniontown. The tornado may have dissipated and redeveloped into a new tornado that crossed into Maryland, killing three people, injuring 25, and destroying seven homes.

In these communities, the tornado destroyed almost 88 homes and damaged 306. Many multi-story dwellings were leveled or torn apart, some single-story residences were also leveled, and more than 400 other structures were damaged or destroyed.
