Parts of Ridge Road in Durham were still dealing with flooding problems hours after the heavy rains stopped.
The rains sent a creek spilling over its banks.
Pools of water also caused some flooding on roadways. Police responded to numerous accidents.
Earlier in the day, tornado watches and warnings were issued for parts of the central and eastern North Carolina.
The National Weather Service says a tornado with a quarter-mile long path and winds of 90 mph knocked down trees and damaged a house near Beaufort, Carteret County. No injuries were reported.
The storms were part of the same system that dumped snow and sleet on the nation's midsection and unleashed damaging tornadoes around the Deep South.
The rare winter twisters damaged numerous homes in Louisiana and Alabama. The vast storm system stretching across numerous states has been blamed for six deaths and several injuries though no one was killed outright in the tornadoes. The storms also left more than 100,000 without power for a time, darkening Christmas celebrations.
Cooler and drier weather will move in for Thursday as winds will be somewhat gusty.
Friday should be dry, but the next storm system will most likely bring wet weather again on Saturday.
