Regional Drought

Take Jamaica, for example, a recent news report suggests that water resources in the Kingston Metropolitan are on the brink of being depleted. To be specific, the report suggests that only One month's supply of water in Corporate Area is available. Except for may be Cuba and the Bahamas, the rest of the Caribbean is experiencing below normal rainfall, and drought conditions could get worse if conditions continue as is. The subtropical jet is further south in El Nino/warm ENSO years, this will generally increase the upper level winds across the Caribbean and the tropical Atlantic, which enhances vertical wind shear across the aforementioned area. These conditions tend to suppress tropical cyclone development, with accompanying dryer than normal conditions in the main development region.
