CDMP Storm Hazard Atlas: Jamaica

Jamaica 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 4.6 at 17 degrees North, and
stretched 5.8 at 19 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.
