Aberdeen, South Dakota – Damaging winds and large hail are possible across northeast South Dakota and western Minnesota today as a Severe Thunderstorm Watch remains in effect until 1 p.m. Wednesday. Motorists and residents in Brown, Spink, Deuel, and 12 other South Dakota counties, along with Big Stone and Traverse counties in Minnesota, should expect rapid changes in weather, with storms likely to bring down trees and power lines.
According to the National Weather Service Storm Prediction Center, the watch—issued at 7:55 a.m.—covers counties including Aberdeen, Watertown, Milbank, and Huron. Officials warn of wind gusts up to 70 mph and quarter-size hail in the strongest storms. Travel on US Highway 12 and I-29 could be hazardous through early afternoon as bands of thunderstorms cross the region.
Local emergency managers advise avoiding unnecessary travel until storms pass and staying alert for rapidly changing weather. Charge mobile devices now, and secure loose outdoor items that could become projectiles. Power outages are possible, especially in rural areas.
Today’s threat follows several rounds of severe weather across the Dakotas this July, echoing last summer’s mid-season storms. More watches or warnings could be issued if storms intensify. The Severe Thunderstorm Watch remains active until 1 p.m.—monitor local alerts and be prepared for additional advisories.
