EF0 tornado in Hamlin County, South Dakota

A tornado touched down over cropland just east of 439th Ave and about a half-mile south of 183rd St. The tornado tracked northeast, crossing 183rd St. Tree damage was noted just before the tornado then crossed 440th Ave. The tornado crossed a farmstead where several empty grain bins were detached from their foundations and destroyed. The last evidence of the tornado was in a crop field roughly a half mile north of this farm and less than a mile southwest of the town of Hazel.

Thunderstorms moving across northeast South Dakota during the early morning hours produced strong winds and wind damage, heavy rainfall, and a brief tornado. A peak wind gust of 80 mph was recorded at the South Dakota Department of Transportation (SDDOT) mesonet station 4 miles west southwest of Stone Bridge, while the SDDOT mesonet station near Turnerville recorded a peak wind gust of 77 mph. Winds were so strong in and around Watertown that the Codington County Emergency Manager reported an innumerable number of trees had fallen across town.
