FEBRUARY 2017 SPI DROUGHT FORECAST FOR JAMAICA

 
 
 
 

Brief Summary:  December signifies the start of the dry season in Jamaica and although the forecast over the period indicates most stations are likely receive near normal to above normal rainfall there could still be problems for some southern and western parishes that are currently receiving below average rainfall amounts.  

The forecast for December to February indicates an increase in the rainfall amounts above the average with greater chance of this occurring in December and January which is mainly due to favourable environmental conditions. We will however continue to monitor the findings from the models in order to advise our farming communities should the situation change and warrant action on their part, especially those farmers over southern and western parishes.
