  1. Tobago Probable Storm Effects 11.55 N Ross Wagenseil for CDMP January 2000 60.35 W 61.0 W 10yr 25yr 50yr 100yr SELECT KILOMETERS MILES ARC-MINUTES Wind 20 CDMP Wave 30 15 Surge 10.9 N 20 10 10 10 5 0 0 0 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 1.8% at 10.9 degrees North, and stretched 2.1% at 11.55 degrees North. All model results were calculated using great-circle distances based on the WGS84 datum. Points of Interest: 1. Scarborough: Main town and harbour. 2. Roxborough: Small town. 2 Tobago Note: Waves and surges for Points of Interest are reported from the nearest cell offshore. Roxborough 1 Scarborough 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 Atlasfor 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.
