The storm comes days after Debby moved up the East Coast unleashing tornadoes and flooding in multiple states.
Hurricane Debby, which entered North Carolina as a tropical storm, weakened into a tropical depression, has moved out of the U.S. over the weekend.
The storm spawned several tornadoes and caused major flooding across North Carolina.
The National Weather Service determined that one tornado that killed a man in Wilson County was an EF-3 strength and another in Sampson County was confirmed as an EF-2 strength.
Those tornadoes are two of at least seven that happened across the state when Debby pushed through the region.
