August Drought Forecast Map

AUGUST 2018 SPI DROUGHT FORECAST FOR JAMAICA

During the period June to August the forecasts are indicating warmer-than-normal temperatures with a chance of below-normal rainfall. During the period the models continue to predict a decline in rainfall amounts across most areas as we transition into the mid-summer drought.

With current projections now indicating a decline in rainfall over most stations over the next three months, there is a possibility that this could lead to occurrence of drought conditions in some areas.

The Meteorological Service will continue to monitor the findings from the models in the upcoming months so as to advise our stakeholders, especially farmers.
