| January 2020 | Tornado (EF0) | Troy | $500,000 | The tornado touched down initially in the southwest portions of the city of Troy and moved northeast through the center of the city. It then crossed the Great Miami River before it weakened and lifted in the far northeast portions of the city.||Much of the damage 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 Great Miami River, where more concentrated and significant tree and roof damage was noted. In particular, areas near Troy High School and along and east of North Market Street saw the most concentrated and higher end structural damage to roofing material. This included 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 wind speeds estimated on the east side of the Great Miami River. |
| July 2022 | Tornado (EF1) | Troy | $100,000 | The initial damage occurred near the intersection of Cheshire Road and Dorset Road, where several large tree limbs were downed. Damage became a little more concentrated near the intersection of Armand Drive and McKaig Avenue, where several large tree limbs and a few trees were downed. Tree damage also occurred at an apartment complex along Red Cedar Drive.||The most heavily concentrated area of damage occurred near Drury Lane and Ridge Avenue. Numerous very large, healthy trees were downed, with one trunk snapped at its base, and several other very large branches snapped not far off the ground. A couple of homes also had some minor roof damage. On West Simpson Street, just to|the east, a car was heavily damaged by a falling tree limb.||The damage path became narrower near Terrace Place, Market Street, and West Street. A bank sign was damaged and several more large trees and tree limbs were downed. In the neighborhood south of West Street, a few more homes had minor roof damage, with a fairly consistent area of tree damage observed as far southeast as Walker Street and Dakota Street.||Tree damage was also reported in other locations in Troy, such as Stanfield Road, West Ross Street, and Dakota Street. The rest of this damage is believed to have been caused by straight-line winds with speeds of 60 to 70 MPH. |
