Sioux Falls, SD – Residents in eastern South Dakota should prepare for severe thunderstorms moving into the region late Monday afternoon, potentially bringing destructive winds, hail, and an isolated tornado threat.
According to the National Weather Service (NWS) in Sioux Falls, thunderstorms are expected between 4 p.m. and midnight Monday, particularly impacting cities like Sioux Falls, Yankton, and Brookings. Primary threats include wind gusts up to 70 mph and hail reaching golf ball-size. The NWS also advises that an isolated tornado cannot be ruled out, especially near the western border areas around Yankton County.
Motorists along Interstate 29, U.S. Route 81, and U.S. Route 18 should remain vigilant for hazardous driving conditions during the evening commute. High winds and hail may significantly reduce visibility and create dangerous road conditions. Residents are advised to secure loose objects outdoors, monitor local emergency broadcasts, and avoid non-essential travel during peak storm hours.
This storm system represents some of the strongest weather the area has experienced this summer season, prompting reminders from emergency officials to have reliable methods of receiving warnings.
Weather alerts may continue into early Tuesday morning as storms progress eastward. Residents should remain alert and ready for rapidly changing conditions throughout the evening.
