November Drought Forecast Map

NOVEMBER 2018 SPI DROUGHT FORECAST FOR JAMAICA

During the period of September to November the forecasts are indicating that most areas are likely to experience near-normal conditions.

Model projections are now indicating that rainfall amounts across the island could remain near-normal with the possibility of declining rainfall amounts in a few isolated areas. While most areas are likely to experience near-normal amount of rainfall, this may not be sufficient to reverse the dry conditions currently affecting sections of the island.

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