Future climate is expected to generate more intense hurricanes compared to the present, leading to more devastating impacts in hurricane-prone regions. Under the prospect of increasing hurricane intensity, risk assessment considering climate change is the first step in planning for hurricane risk mitigation strategies. In this study, climate-dependent regional hurricane risk is assessed for eight counties extending across the U.S. south and east coast. A hurricane impact model is developed and used to assess the regional hurricane risk by considering population vulnerability. It is found that hurricane risks in the future climate are higher than the present for all the counties, though the degree of increase is found to differ across the counties. It is also observed that the demographic composition of a region has an appreciable influence on the regional hurricane risk.
