Service Description: This map service represents modeled, historical exposure of U.S. offshore, coastal, and international waters to tropical cyclone activity within the North Atlantic Ocean basin (1900-2016). BOEM Outer Continental Shelf Lease Blocks and equivalent areas for coastal and international waters were used to construct the grid by which exposure was quantified. Exposure was quantified using intersecting storm tracks, overlapping wind intensity areas, and mathematical return intervals. Symbology is based on the modeled occurrence of hurricane force (64-knot) or greater winds per grid cell. 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. Data represent past climatology only and do not suggest predicted future impacts or exposure. If you plan to ingest this service into your own application and would like to be informed about planned and unplanned service outages or changes to existing services, please register for our Data Services Newsletter.
