Marion is a Cedar Rapids suburb in Linn County that was among the hardest-hit communities in the August 2020 derecho — a catastrophic straight-line wind event that produced winds exceeding 140 mph and caused more than $11 billion in damage across Iowa. The city also shares Cedar Rapids' Cedar River flooding exposure and tornado risk. The 2020 derecho demonstrated that non-tornado wind events can be equally or more destructive than tornadoes.
