BISMARCK, N.D. (AP) — Utility crews are working to restore power to hundreds of people in northwestern North Dakota after a round of storms smacked the region with heavy rains, high winds and hail. The Bismarck Tribune reports the storm swept through Thursday night. Some areas received as much as four-and-a-half inches of rain. Williams County saw flash flooding. Part of a truck wash collapsed in Williston. That area also saw hail as large as two-and-a-half inches in diameter. At least two tornadoes were sighted in McKenzie County and winds as strong as 79 mph gusted at Long Lake National Wildlife Refuge near Moffit. Montana-Dakota Utilities crews worked to restore electricity to 7,500 customers across the Dakotas and eastern Montana.
