Barbuda Probable Storm Effects The projection of the illustrations is Plate Carrée, a square grid of latitude and longitude. Resolution is 30 arc-seconds. North-South distances are true to scale. East-West distances are stretched 4.8% at 17.4 degrees North, and stretched 5.1% at 17.9 degrees North. All model results were calculated using great-circle distances based on the WGS84 datum. Note: Waves and surges for Points of Interest are reported from the nearest cell offshore. This set of maps is part of Section 2 of the Atlas of Probable Storm Effects in the Caribbean Sea, which was sponsored by the Caribbean Disaster Mitigation Project (CDMP), a joint effort of the Organization of American States (OAS) and the US Agency for International Development (USAID). These maps are a result of new techniques for modeling storms and estimating the probabilities of storms, developed in part under the patronage of CDMP. Refer to the Atlas for explanatory materials.Atlas of Probable Storm Effects in the Caribbean SeaAtlas WINDS represent sustained 1-minute winds at 10 m above the surface, and include both surface friction and topographic effects at a resolution of 30 arc-seconds. Friction factors derive from a Level I land-cover classification, with water, forest and open land predominating. If using wind damage models or building codes which internally include surface friction or topographic corrections, the nearest open-water wind speed from one of these maps may be used as input. Careful judgement is advised in reading and applying the values. SURGES include astronomical tide and setups from pressure, wind and wave, but not wave runup. Surges over land are shown as elevation above sea level, not water depth. WAVES are the heights of wave crests above the storm surge level in open water. Shoreline effects do not appear at this resolution.
