Storms and Tornadoes

The heavy rainfall and storms are part of a weather system that earlier this week brought tornadoes to Pilger in Nebraska, where one person died and 19 were injured people. The town itself sustained extensive damage, with a reportedly 50-70% of buildings and infrastructure damaged or destroyed. The storms and torrential rainfall of Monday and Tuesday were followed by a tornado warnings for parts of South Dakota late Tuesday 17 June 2014.

Canton, south Dakota, was also badly hit by flooding. In fact flooding was so bad, the Interstate 29 near the Canton exit had to be closed during the evening of16 June 2014.

For some time during Monday and Tuesday, the small city of Canton was cut off from the outside world by flood water. The flooding spread across the area, affecting Harrisburg, South Dakota, and the wider areas of Lincoln and Turner counties.
