ABERDEEN, S.D. (KELO.com) — South Dakota experienced its second derecho storm of this year’s severe weather season on Tuesday.
A derecho is defined as a straight-line wind storm that extends more than 240 miles and includes wind gusts of at least 58 miles per hour.
Most of the worst of the storm occurred south of Aberdeen in more central and east-central South Dakota.
Megan Mulford with the National Weather Service in Aberdeen says the meteorology term derecho has been around for a long time, but this has been an abnormally active severe weather season.
She said the worst winds were recorded by Howard and softball-sized hail by Promise.
Mulford says it could take weeks to assess the full damage the storm brought on the state.
