MARSHALL — A powerful line of severe thunderstorms could sweep across the Northern Plains today, potentially forming a derecho capable of producing wind gusts over 75 miles per hour, large hail, and a few tornadoes.
The highest threat area stretches from South Dakota into southern Minnesota and northern Iowa. Forecasters say storms may organize into a long-lasting line this afternoon and evening as they follow the northern edge of a heat dome affecting the central United States.
Potential impacts include widespread wind damage, downed trees, structural damage, and power outages.
If a derecho forms, it would be the second to hit the region this summer. A similar storm in late June brought gusts over 100 miles per hour and several tornadoes to parts of North Dakota and northern Minnesota.
Officials urge residents to prepare now by identifying safe shelter locations and ensuring they have multiple ways to receive National Weather Service alerts, including smartphone notifications and NOAA weather radios. People in mobile or manufactured homes should plan ahead to reach a sturdier structure quickly if warnings are issued.
