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 4.9 at 17.5 degrees North, and
stretched 6.6 at 20.17 degrees North. All model
results were calculated using great-circle
distances based on the WGS84 datum.

• 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.
