A line of severe thunderstorms packing hurricane-force wind rumbled across the Midwest on Monday, damaging homes and farms, downing trees and destroying an airplane hangar.
One person was injured overnight near Hayes, South Dakota, where a wind gust was measured at 122 mph, the strength of a Category 3 hurricane, The Weather Channel reported, citing the National Weather Service.
Storm damage was also reported in Iowa, Indiana, Minnesota and Wisconsin. Near Sheldon, Iowa, a hangar was demolished and planes were damaged from winds gusting to 95 mph. Interstates 65 and 69 were closed in parts of Iowa because of downed power lines or debris.
The Weather Channel classified it as a derecho, a weather phenomenon that can do as much destruction as a strong tornado. A derecho is a line of especially powerful winds that causes damage for at least 240 miles.
The weather service posted a severe thunderstorm watch for Detroit as the storms pushed east. In Chicago, more than 500 flights were canceled, according to the tracking site FlightAware.
A high school in Independence, Iowa, clocked a gust of 93. A tree crashed onto a car in Plymouth, Iowa, trees came down in Whitestown, Indiana, and farming facilities were damaged across northern Iowa.
Forecasters said a swath of the country from Maine to the Carolinas, and west to Tennessee and Kentucky, would be at risk of severe thunderstorms on Tuesday.
