Des Moines was devastated by the August 2020 derecho — a massive inland hurricane-force wind event that caused $11 billion in damage across Iowa. The event destroyed millions of acres of crops and caused widespread structural damage across the city. The Des Moines and Raccoon Rivers also create significant flooding risk — the 2008 Iowa floods inundated much of downtown Des Moines. Iowa's agricultural economy means major weather events have cascading national food supply implications.
