Wilmington is one of the wettest large cities in the eastern US at 66 inches annually; direct hurricane exposure from the Atlantic; Cape Fear River creates an extensive floodplain; Hurricane Florence (2018) dumped 36 inches in 3 days; sea level rise is measurably increasing tidal flooding frequency each year
Flood-prone areas: Sunset Park, Holly Tree, and all communities west of US-17 in the Cape Fear floodplain face highest storm surge and river overflow risk
