Multiple clusters of storms moved across portions of central, north central and northeast South Dakota on the morning of July 23rd. Many of these storms produced strong winds and wind related damage.

Thunderstorm winds were also responsible for damage grain bins and the Agtegra building near the town of Carpenter.
