September Drought Forecast Map


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

This rainfall outlook is particularly significant because all parishes with the exception of Trelawny are experiencing Meteorological Drought conditions. The months of May and June are traditionally characterized by an increase in rainfall which would typically reduce water deficits resulting from reduced rainfall during the dry season. From observations, all parishes experienced increasingly drier conditions throughout these months. Current and projected environmental conditions continue to point toward a warmer and dryer Caribbean, including Jamaica.

Therefore, Jamaicans should brace for an increase in heat stress impacts, more bush fires as well as reduced water inflows into water storage facilities and reservoirs for the upcoming three-months.

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.
