The Iowa Supreme Court has ruled in a case that defines the definition of rain when it comes to insurance claims. The Amish Connection Store in Crossroads Mall in Waterloo was flooded after a corroded drain pipe carrying rainwater through the building burst during a heavy rainfall in 2010. State Farm insurance refused to cover the losses, citing a provision in its policy that loses for rain are only covered if there is first damage from a storm that allows the rainwater to get into the structure.
