Trinidad and Barbados were abnormally wet; Tobago, Grenada, and St. Lucia moderately wet; Guyana from extremely wet in the north to normal in the east; St. Vincent and Dominica normal; Antigua and Anguilla; moderately dry; and St. Kitts and St. Croix abnormally dry.

Apart from the extreme east of the country that was abnormally wet, Cuba was predominantly normal; and so too was the Cayman Islands.

Trinidad was moderate to very wet; Tobago extremely wet; Grenada, Barbados, St. Vincent, Antigua and Anguilla normal; St. Lucia abnormally wet; St. Kitts moderately wet; Dominica and St. Croix moderately dry; and Guyana abnormal to moderately wet. Puerto Rico was abnormally wet in the west and normal in the east, while the Dominican Republic ranged from extremely wet in the northeast to moderately wet moving out toward the ourskirts. Conditions in Jamaica ranged from abnormally dry in the west to abnormally wet in the east, while Cayman Islands was normal. The western half of Cuba was predominantly normal, but the eastern half ranged from normal to extremely dry. Conditions in Belize ranged from moderately dry in the south to moderately wet in the north.

Note:

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. During December, some relief has been experienced to the very dry conditions prevailing in the south eastern Caribbean.
