Overview
|
Storms impacted parts of the region Friday afternoon and evening, August 27, 2021. Hardest hit areas were northeast Iowa where at least 2 tornadoes occurred in addition to rounds of heavy rain. A set of storms tracked across southern Floyd County, IA and produced tornadoes near Marble Rock and Greene, IA. One tornado (rated EF1) heavily damage a few farms. Damaging winds hit several other communities, especially between Calmar and Postville, IA where crops were flattened and some buildings sustained damage. Rainfall of 3 to 8 inches also led to significant flooding over northeast Iowa. Area rivers flooded which led to the closure of many area highways, including US Highway 18 near Fredericksburg and New Hampton, IA. Secondary roads were also damaged and several homes were flooded. Information is preliminary and may be adjusted. |
