Risk Overview
About Natural Disaster Risk in Orange County, North Carolina
Orange County's risk is moderate nationally
Orange County's composite risk score of 79.07 and 'Relatively Low' rating position it below many U.S. counties in overall natural disaster hazard. However, localized flood and tornado risks merit attention from homeowners and planners.
Moderate risk within North Carolina
At 79.07, Orange County exceeds the state average of 66.72, reflecting its Piedmont location and exposure to river flooding and severe thunderstorms. Inland geography spares it from hurricane storm surge but not from the inland impacts of tropical systems.
Riskier than many Piedmont neighbors
Orange County (79.07) carries higher total risk than many surrounding Piedmont counties, driven primarily by its flood risk of 85.53. However, its wildfire risk of 28.44 is significantly lower than coastal counties to the east.
Flooding and tornadoes dominate the hazard profile
Orange County's flood risk of 85.53 is among the highest in the state, reflecting rivers and streams that swell during heavy rains and tropical system remnants. Tornado risk of 81.46 reflects springtime severe weather typical of the Piedmont region.
Prioritize flood protection and weather awareness
Orange County residents, especially those in flood-prone areas near streams and rivers, should obtain flood insurance if in a Special Flood Hazard Area. Maintain a severe weather kit, sign up for emergency alerts, and identify a safe interior room for tornado shelter.
