The National Weather Service says warmer temperatures over the next few days will melt the snow on the ground and the ice covering Iowa rivers.
All that melting could cause ice jams, putting some parts of the state at risk for flash flooding.
An area just north of Fort Dodge on the Des Moines River has seen first-hand the damage ice jams can cause.
Tall prairie grass and broken branches now cover an area once occupied by several homes.
“We had such severe damage we applied to FEMA for a buyout of the homes in this area,” said Tony Jorgensen, the emergency manager for Webster County.
In February of 2011, Jorgensen says a fast warm-up melted the ice covering the river.
Ice chunks flowed downstream and jammed up the river when they reached narrow areas.
Melting snow had no other place to go, and flooded nearby homes.
