Even though the official start of winter is nearly a month away, a wintry storm was developing in the northern part of the United States on Tuesday, with snow falling in North Dakota.

As much as 8 inches (20 centimeters) of snow had fallen by late Tuesday afternoon in parts of North Dakota and South Dakota, according to the National Weather Service.

In North Dakota, officials closed parts of Interstate 94 and Interstate 29 due to ice, low visibility and multiple accidents.
