Derecho Flattens Iowa Crops
"A powerful windstorm, known as a derecho, tore across Iowa, northern Illinois, and northern Indiana on Aug. 10, 2020, with hurricane-force winds of 75 mph (120 kph) or more. Eastern Iowa saw gusts of up to 115 mph (185 kph), according to the National Weather Service. These images show fields of corn and soybeans in that state, before and after the storm. The lighter greens of the August image indicate crops that the winds damaged."
