A slow moving area of low pressure which had brought heavy snow to western South Dakota affected eastern South Dakota on April 21st and 22nd, 1992. As the large storm moved east across the state it brought heavy snow and ice accumulations with it. Freezing rain or sleet preceded the snow across much of the east laying down a slick glaze of ice. On top of the icy roadways 6 inches to a foot of wet snow piled up making traveling very hazardous. The slick roads resulted in many accidents across eastern South Dakota as well as northwest Iowa and southwest Minnesota. Winds gusting to around 50 mph only made travel more difficult. Many towns in southwest Minnesota lost power due to the heavy icing...some areas were without electricity for over 5 hours. Some snowfall amounts across the east included 10 to 12 inches in the Marion and Elk Point areas in Southeast SD and around 9 inches near Vermillion.
