In the eastern Caribbean and Guyana Trinidad was moderately wet; Tobago very wet; St. Kitts moderately wet; Grenada, Barbados, St. Vincent, St. Lucia, Antigua and Anguilla normal; Dominica moderately dry; St. Croix severely dry; and Guyana normal except for the extreme north. Puerto Rico was normal. Conditions in the Dominican Republic ranged from moderately wet to very wet in central areas, but in Jamaica the range was from abnormally dry in the west to abnormally wet in the east. The majority of Cuba was normal to abnormally dry, but reached extreme dryness in eastern Cuba. Cayman Islands was normal, but conditions in Belize ranged from moderately dry in the west to abnormally wet in the north.

Note:

Interest in the western Caribbean should pay particular attention to water availability and monitor water resources as predominantly dry conditions prevailed in many areas of this part of the basin over the past few months. This is made even more important as normal to below normal dry season rainfall are predicted for the next three months. The northern portion of the eastern Caribbean should take similar precautions, even though normal to above normal conditions are expected during January to March 2013. More specifically therefore, Belize, Cayman Islands, Cuba and Jamaica in the west and from Dominica northward to St. Croix should take precaution.
