A tornado damaged homes and docks at Lake Lotawana Tuesday afternoon, the National Weather Service confirmed.

Deputy Raashid Brown of the Jackson County Sheriff's Office said a mid-day storm around Lake Lotawana damaged several homes and caused power outages.

Brown said that there were no injuries.

The National Weather Service confirmed that an EF-0 tornado traveled 3.4 miles on the ground, that its maximum width was 100 yards and that its wind speed reached about 80 mph. It started near Cyclone School Road just north of Colbern Road. It traveled southeast, crossing Colbern Road, then Missouri 7 and Lake Lotawana before ending near the lake’s eastern shore.

The storm damaged several roofs, brought down tree limbs and power lines and damaged docks and boats. More tree damage was reported near Missouri 291 and Independence Avenue in northern Lee’s Summit.

Johnson County, Missouri, sustained damage from the same storm. Troy Armstrong, director of emergency management for Johnson County, said at least one outbuilding was destroyed, power lines were downed, homes were damaged by fallen trees and some road flooding was reported.
