Heavy precipitation with rapid cooling produced a combination of freezing rain, sleet, and snow over all of southeast South Dakota from the early morning hours of April 9th, to the morning of April 11th. Moderate to heavy ice accumulations were reported near Interstate 90. These were followed by moderate to heavy snow and sleet accumulations, mainly near and north of Interstate 90. The ice accumulations, greater than a half inch in some areas, caused major tree and power line damage in the ice storm area. Fallen branches and limbs were numerous, trees were destroyed, roads were blocked, and some vehicles and homes suffered damages from the falling trees, limbs, and branches. There were also major power outages because of the power line and power pole damage. Strong winds with and following the storm, not strong enough to cause significant damage under dry conditions, contributed greatly to the tree and power line damage. The snow and sleet accumulations made travel difficult, especially in areas where downed trees and power lines were already causing road blockages.
