Unseasonably high moisture interacted with a stationary, weakening frontal boundary to produce heavy rainfall across western North Carolina throughout the 11th. Flash flooding developed along several basins across the northern mountains after 4 to 7 inches of rain fell in around 24 hours, with roughly half of that falling within a few hours during the morning.
