| Abstract: | Hurricanes are one of the major natural disturbances affecting human livelihoods in coastal zones worldwide. Assessing hurricane
risk is an important step toward mitigating the impact of tropical storms on human life and property. This study uses NOAA’s
historical tropical cyclone database (HURDAT or ‘best-track’), geographic information systems, and kernel smoothing techniques
to generate spatially explicit hurricane risk maps for New England. Southern New England had the highest hurricane risk across
the region for all storm intensities. Long Island, western Connecticut, western Massachusetts, and southern Cape Cod, Martha’s
Vineyard, and Nantucket had high storm probabilities and wind speeds. Results from this study suggest that these locations
may be of central importance for focusing risk amelioration resources along the Long Island and New England coastlines. This
paper presents a simple methodology for hurricane risk assessment that could be applied to other regions where long-term spatial
storm track data exist. |
