April Drought Forecast Map


The outlook for the upcoming three-month period of February to April shows that rainfall totals are likely to be near-normal. Although, the forecast indicates that most areas across the island could experience average rainfall amount. The forecast also indicated, that sections of Portland and St. Mary which are already experiencing a notable degree of drying, could continue to see deficits in rainfall amounts with possible drought impacts. The forecast for temperature during the period remains above-normal but, seasonally comfortable.

The Meteorological Service continues to implore our stakeholders to take immediate action to minimize the negative effects of water shortages during the dry season. Farmers and householders, in particular, should consider rainwater harvesting (along with its proper storage) during occasional wet days and employ water conservation methods when possible.

The Meteorological Service will continue to provide updates for the upcoming months.
