Flood waters run over Interstate 90, two miles west of Mt. Vernon on Thursday, Sept. 12.
South Dakota is in the midst of its wettest year on record and Mitchell has seen its third-wettest year after historic spring and summer rains swamped fields and flooded cities, roads and homes throughout the state.
"I think the story of the year is precipitation," said Laura Edwards, state climatologist for South Dakota. "Statewide we already have the wettest season on record, and we still have five or six weeks to go. That doesn't even count November."
Edwards said South Dakota has received a statewide average of 29.37 inches of precipitation so far this year. The previous wettest season in the state was in 1915, when 27.97 inches of precipitation fell.
Weather statistics from the National Oceanic and Atmospheric Administration indicate the Mitchell area has received 34.09 inches of precipitation so far in 2019, which already ranks it as the third-wettest year for the area. The highest amount of precipitation recorded in Mitchell for a full year was in 1993, when the area received 36.19 inches of precipitation, and in 1908, when 36.14 inches of precipitation was recorded.
