A National Weather Service damage survey in collaboration with Miami County
Emergency Management Agency and Troy Fire Department confirmed a weak tornado
touched down initially in the southwest portions of the city of Troy, and
moved northeast through the center of the city, crossing the Great Miami River
before weakening and lifting in the far northeast portions of the city.

Much of the damage surveyed was confined to trees and roofs, both residential
and commercial as the tornado moved through the city. To the west of the Great
Miami River, damage was more intermittent and weak in comparison to areas
east of the Miami River where more concentrated and significant tree and roof
damage was noted. In particular, areas near the Troy High School and then along
and along and east of North Market Street saw the most concentrated and
higher end structural damage to roofing material. This includes the far eastern
portions of the downtown area which saw several businesses lose all or portions
of their roofs.

Damage was tornadic in nature, especially on the east side of the Great
Miami River where convergent tree damage was easily noted before the
tornado rapidly weakened as it left the city.  Damage along the path
was consistent with wind speeds ranging from 65 to 80 mph, again with
the highest windspeeds estimated on the east side of the Great Miami River.
