Two tornadoes that killed six people in North Dakota and New York each had wind speeds topping 100 mph and caused brief but widespread damage as they tore through largely rural areas, officials said.

The severe storms caused significant damage to homes and infrastructure in several parts of eastern North Dakota.

At least three people were killed in a small North Dakota town as tornadoes ripped through the state. All three victims lived in Enderlin, a town of 800 residents about 40 miles southwest of Fargo, according to the Cass County sheriff’s office. They have been publicly identified only as two men and a woman.
