Residents and drivers along the South Dakota-Nebraska border should stay alert this evening as a Severe Thunderstorm Watch remains in effect until 10 p.m. Tuesday. The watch warns of potential damaging winds, large hail, and power outages as thunderstorms develop in the region.
Areas Affected
According to the National Weather Service Storm Prediction Center, the Severe Thunderstorm Watch covers several counties in southeast South Dakota, including Aurora, Bon Homme, Brule, Charles Mix, Clay, Davison, Douglas, Gregory, Hanson, Hutchinson, McCook, Turner, and Yankton. In Nebraska, Boyd, Cedar, Holt, Keya Paha, Knox, and Rock counties are also under the watch. The greatest risk is expected between 6 p.m. and 10 p.m., with thunderstorms potentially affecting major highways like U.S. 81 and U.S. 18.
Thunderstorm Threats
Residents in towns such as Yankton, Vermillion, and O’Neill should prepare for sudden downpours, gusty winds, and the possibility of large hail. With severe storms, conditions can change rapidly, so outdoor plans should be rescheduled, and vehicles should be moved indoors where possible. Emergency management teams recommend securing loose items, staying away from windows, and ensuring cell phones and flashlights are fully charged in case of power loss.
Travel and Road Conditions
Storms could cause deteriorating road conditions quickly, with reduced visibility, standing water, and potential debris. Drivers are urged to monitor local weather alerts, stay updated on potential detours, and be prepared for road closures. It’s important to avoid unnecessary travel during the storm.
Relief and Additional Threats
The severe weather threat is expected to diminish after 10 p.m., but there is still a possibility of further watches or warnings if the storms persist into the overnight hours. Residents should remain alert for any updates.
