March Drought Forecast Map


Brief Summary:   December through March represents the dry season for Jamaica. The rainfall outlook for January to March 2017 is reflecting near normal or what would be considered climatology with warmer days.

There was significant deficit in rainfall for Hanover and Westmoreland for October and November and likely for December as well due to the lack of significant rainfall activity during the month. Shortfall in activity was also seen in some southern parishes.

Western and southern parishes are therefore likely to experience some level of drying for January through March due to the forecast showing reduced rainfall activity which is likely to exacerbate the existing deficit.
