August Drought Forecast Map

AUGUST 2020 SPI DROUGHT FORECAST FOR JAMAICA

The forecast for the upcoming three-month period June to August 2020 from the CPT indicates that rainfall amounts are likely to be below-normal to near-normal, with above-normal temperatures.

Insufficient rainfall in recent months has resulted in drier conditions affecting sections of most parishes and this trend could continue over the coming months. We are at the start of another Hurricane Season, which is predicted to be active and should produce an above-average number of tropical cyclones over the region comprising of the North Atlantic Ocean, the Gulf of Mexico and the Caribbean Sea. As Summer approaches, warmer than normal temperatures are expected and should be more noticeable on days with little or no rainfall.

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