Sioux Falls, South Dakota – South Dakota is bracing for widespread heavy rain that is expected to begin late Tuesday night, with up to 4 inches of rainfall possible across the region. Flooding concerns are growing as the storm system continues to move through the area, with the threat lasting through Thursday.
Rain and Flooding Impact Across the Region
According to the National Weather Service (NWS) in Sioux Falls, an active weather pattern will bring repeated rounds of rain to southeast South Dakota, southwest Minnesota, northwest Iowa, and northeast Nebraska.
Rainfall totals of 2 to 4 inches are expected, with some areas, particularly northeast Nebraska and northwest Iowa, possibly seeing even higher amounts.
Cities such as Sioux Falls, Yankton, and Norfolk could experience urban flooding and small stream flooding, especially as the rain continues to fall over the next couple of days.
Local authorities are urging residents to stay away from flooded roads, particularly during the overnight hours when visibility may be reduced.
Additional Severe Weather Threats
In addition to heavy rain, there is a risk for minor hail and strong storms on Wednesday. The storm system could also produce an isolated tornado, so residents should stay alert for any weather warnings or updates.
The potential for rapidly changing weather conditions will be especially concerning for travelers along highways such as I-29, Highway 81, and rural farm routes. Flooding is possible on these roadways, so drivers should prepare for dangerous conditions and avoid water-covered streets.
Preparedness and Safety Measures
Local emergency management officials advise residents to prepare for the heavy rain by charging electronic devices, reviewing flood safety plans, and keeping an eye on local alerts for updates.
It’s important to stay informed, as the situation could change quickly, and additional updates are likely as rain bands continue to develop throughout the region.
