Officials in Greensboro, North Carolina, said one person was killed Sunday after a tornado struck the city, part of a severe storm system that also dumped two feet of snow on parts of the Upper Midwest and knocked out power to hundreds of thousands.

Greensboro police gave no immediate details about the death. However, Fox 8 reported the victim was a motorist who was hit by a falling tree. Authorities declared a state of emergency in the city after high winds reportedly damaged at least seven homes and destroyed one mobile classroom.

About 75,000 homes and businesses were without power late Sunday afternoon in the Carolinas. Duke Energy said about 43,000 customers lacked power in North Carolina, and another 9,000 in South Carolina. South Carolina Electric and Gas Company reported 23,000 customers without power in South Carolina.

The airport in Charlotte said on Twitter Sunday that severe weather briefly caused a ground stop and forced air traffic controllers to leave their tower. The ground stop was later lifted.

The Greensboro death is at least the fourth to be blamed on the storm system which has stretched from the Gulf Coast to the Great Lakes.

A sleeping 2-year-old girl in Louisiana was killed when a tree fell on her family’s recreational vehicle early Saturday. A Wisconsin woman was killed when she lost control of her minivan on slick roads and veered into an oncoming SUV. And an Idaho truck driver was killed when his semitrailer struck a semi in western Nebraska that had been stranded on a highway by the bad weather.
