Severe storms and flash flood threats target Midwest and Plains
US · Published Aug 17, 2026
A multiday severe weather event is unfolding across the Midwest and Plains, bringing threats of damaging winds, hail, isolated tornadoes, and flash flooding.
The event begins late Monday afternoon in eastern North Dakota, west-central Minnesota, and the Black Hills, with hail as the primary concern.

Impact & Risks

The severe weather poses significant risks to communities across the Midwest and Plains. Damaging wind gusts, hail, and isolated tornadoes could lead to property damage and power outages. Flash flooding is a major concern, especially in areas with saturated ground from previous storms, such as Iowa, Nebraska, and Illinois. Tropical-like moisture levels and intense rain rates may exacerbate flooding, potentially causing infrastructure damage, evacuations, and water rescues. Areas in the Ohio Valley, still recovering from last week's catastrophic flooding, may face renewed challenges as storms shift southeast later in the week.
