JUNE 2017 SPI DROUGHT FORECAST FOR JAMAICA

Brief Summary:  As we enter into what is considered the secondary rainfall season, the forecasts are indicating near normal to below normal rainfall across most stations. During Jan-Mar, drought affected sections of some western and central parishes due to steady declines in rainfall amounts.

However, with current projections now indicating a decline in rainfall over the next three months, there is a possibility that this could lead to more widespread occurrence of drought as well as worsened drought conditions in areas which were already reporting drought.
