Overview

An early morning storm system impacted parts of central and east central South Dakota. While large hail fell in the Pierre area, parts of Hamlin and Deuel counties were the hardest hit. This area experienced winds in the 80 to 90 mph range, along with large hail. Northwest of Castlewood multiple power poles were downed blocking the intersection of Highways 81 and 22. In the city of Castlewood winds caused structural damage, tree damage, and the wind-driven hail broke through windows and punched holes in siding. The assisted living was evacuated due to damage on the north end of the building. No travel was advised in the city due to debris blocking roadways. Further southeast, hail up to the size of golf balls damaged homes in the town of Astoria. Significant crop damage was also noted along the path of this storm.
