The Grenadines St. Vincent 13. 2 N Probable Storm Effects Bequia Admiralty Bay 1 Points of Interest: 1. Admiralty Bay: Deep-water harbour with village. Values listed are for a cell out to sea on the west, since the harbour does not appear at this resolution 2. Hillsborough: Village on a shallow lagoon. Canouan Mayreau Note: Waves and surges for Points of Interest are reported from the nearest cell offshore. Union Note: Several small islands appear co-joined at this resolution.

North-South distances are true to scale. East-West distances are stretched 2. 3% at 12. 15 degrees North, and stretched 2. 7% at 13. 2 degrees North. All model results were calculated using great-circle distances based on the WGS 84 datum.

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.
