Most accumulations were in the 2 to 5 inch range with the highest totals around 5 inches at Lock and Dam 10 near Guttenberg (Clayton County) and 4 inches north of Frankville (Winneshiek County). Strong winds of 30 to 45 mph from the 23rd into the 24th created blowing and drifting snow. Whiteouts were common and blizzard conditions occurred across Floyd, Chickasaw and Fayette County. Numerous rural roads were drifted shut across these counties. State snow plows were pulled off the roads across all of the region for the evening of the 23rd into the early morning of the 24th.
