June 16, 2010 Tornadoes in Dupree, SD

During the late afternoon and evening Wednesday, June 16; a slow moving thunderstorm produced tornadoes, damaging straight-line winds, and flooding in and around Dupree, South Dakota.  Law enforcement, storm spotters, and storm chasers observed more than ten tornadoes from southwest of Dupree to north of town. Multiple tornadoes were on the ground at the same time. A storm survey conducted by the NWS determined the damage in Dupree was caused by a combination of straight-line winds and tornadoes. The tornadoes in the town of Dupree were likely rain-wrapped and not visible, and due to the widespread damage from straight-line winds the exact tracks of the tornadoes could not be determined, although damage pattern did reveal tornadic rotation. The extent of the damage to several houses, mobile homes, and the community center indicated wind speeds of 120 to 130 mph, which is classified as an EF-2 on the Enhanced Fujita Scale.

Four to six inches of rain produced widespread flooding across the area, causing many roads to become impassable. Water flowed over U.S. Highway 212 in several locations and in some places was estimated to be over a half mile wide.
