FEBRUARY 2020 SPI DROUGHT FORECAST FOR JAMAICA

The forecast for the upcoming three-month period December 2019 to February 2020 indicates that rainfall amounts are likely to be below-normal with seasonally comfortable temperatures. This rainfall outlook is not the most favourable for some sectors including agriculture; especially since December marks the beginning of the island’s dry season. Employing water conservation methods may prove quite useful for the upcoming period.

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.
