Yankton, Clay, Union and Lincoln counties are under a blizzard warning, as is northwestern Iowa and Nobles County in Minnesota. Minnehaha County is under a winter storm warning. Scroll down for watches and warnings map. 

In the areas of the blizzard warning, 40 mph wind will cause whiteout conditions. Up to 18 inches of snow is possible in isolated areas.

Snow will start in eastern South Dakota around 6 p.m. Sunday evening, with heaviest rates overnight into Monday morning. The National Weather Service advises that there will be "significant impacts to travel and outdoor activities."
