MAY 2017 SPI DROUGHT FORECAST FOR JAMAICA

 

Brief Summary:  The rainfall outlook for March to May 2017 indicates that most stations examined will likely receive near normal to below normal rainfall during the period. As the decline in rainfall is now spreading to other parishes there could be increased incidences of drought. In particular areas which were already recording drying may have worsened conditions.  

The Meteorological Service will continue to closely monitor the rainfall activities across southern and western parishes over the next three months. This is to ensure that critical and sensitive sectors such as agriculture which depends heavily on rainfall can adjust plans as necessary, in order to handle possible shortfall in water availability.
