Wilmington is North Carolina's most hurricane-exposed city. Florence (2018) essentially isolated the city for a week — roads were impassable, and power was out across the region. Duke Energy serves the area, and extended outages after tropical systems are the norm. Since Florence, Wilmington has one of the highest per-capita generator installation rates in North Carolina.
