At least nine people were injured in vehicle accidents across Allamakee County that occurred in dense fog on January 11th. Two people were injured in a two vehicle crash in Waukon when the driver of the first vehicle pulled into the path of the second vehicle, which they did not see because of the dense fog. A glaze of ice was also present on some roads where the fog occurred with temperatures below freezing or where recent snow melt refroze. These icy conditions caused a school bus to slide through an intersection and down an embankment injuring 7 people. One of the students injuries were severe enough to require being transferred to a larger hospital for further treatment. Numerous other minor accidents also occurred across the county. The automated weather reporting equipment at the Decorah airport reported a visibility of a mile or less in fog from around midnight January 11 until late in the afternoon.
