Understanding Risk Factors for Duncan
🌀 Hurricane Risk
Duncan is vulnerable to Atlantic hurricanes and tropical storms, particularly during the June–November season. While direct hits from major hurricanes are less frequent than in the Gulf states, nor'easters and weakening tropical systems can cause significant flooding and wind damage. Coastal erosion from repeated storm events is an ongoing concern.
🌊 Flood Risk
Duncan faces significant flood risk due to its coastal location. Storm surge from hurricanes and tropical systems can push water miles inland, while heavy rainfall events strain local drainage systems. FEMA flood zone maps identify multiple high-risk areas, particularly in low-lying neighborhoods near the coastline and waterways.
💨 Air Quality
Air quality monitoring in Duncan draws from EPA AirNow sensors measuring particulate matter (PM2.5), ozone levels, and other pollutants that affect respiratory health. Seasonal variations and agricultural or industrial activity can influence local air quality.
🔥 Wildfire Risk
Wildfire risk evaluation considers vegetation density, climate conditions, historical fire data, and terrain characteristics in Duncan. Seasonal weather patterns and local land management practices influence the area's fire vulnerability.
