Resolution is 30 arc-seconds. North-South distances are true to scale. East-West distances are stretched 4.9% at 17.5 degrees North, and stretched 6.7% at 20.33 degrees North. All model results were calculated using great-circle distances based on the WGS84 datum. Points of Interest: 1 Cap Haïtien Gonaïves 1. Cap Haïtien: Town and port. 2 2. Gonaïves: Town and port. Haiti 3. Port-au-Prince: Capital city. 4. Les Cayes: Town on shallow bay. Dominican Republic Note: Waves and surges for Points of Interest are reported from the nearest cell offshore. Port au Prince 3 Les Cayes 4 N • 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. • 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.
