July Drought Forecast Map

JULY 2018 SPI DROUGHT FORECAST FOR JAMAICA

As we enter into what is considered the secondary rainfall season, the forecasts are indicating warmer than normal temperatures with a chance of above-normal rainfall. During January-March, there were no reports of drought as the island experienced an increase in rainfall across most parishes.

Although, with current projections now indicating a decline in rainfall over some stations compared to the average over the next three months, there is a possibility that this could lead to isolated occurrence of drought conditions in selective 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.
