Tropical cyclones frequently affect the offshore and coastal waters of the United States, with exposure varying by storm, year, and locality. Using data developed by MarineCadastre.gov, this story map highlights the modeled historical exposure of U.S. marine waters and coastal states to tropical cyclone activity for the period of 1900 to 2016. Exposure metrics used throughout this story map represent past climatology only and do not suggest predicted future impacts or exposure. There can be high uncertainty about when a hurricane may strike a specific locality. Furthermore, this investigation does not take into account the occurrence of nor'easters.Due to the way winds were calculated differently over land and over water, the interpretation of wind exposure metrics within coastal areas should be interpreted carefully.Access to these data are provided by MarineCadastre.gov, a joint Bureau of Ocean Energy Management and National Oceanic and Atmospheric Administration initiative providing authoritative data to meet the needs of the offshore energy and marine planning communities.
