Note:

Interest in the western Caribbean, more specifically Belize, Cayman Islands, Cuba and Jamaica, 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 and is likely to persist during March into April. The concern over severely dry conditions in the northern portion of the eastern Caribbean has intensified, and in fact has expanded its geographical area further south, and all the way to Grenada. Interests in these areas should take precautions against severely low water levels. Some countries may have to issue drought and water watches or alerts if conditions continue to persist during March as expected.

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.
