Brief Summary:  Through the period April to June the models continue to indicate an increase in the forecasted rainfall amount across most areas. As we approach the secondary rainfall season, the expected increase in rainfall activities is likely to ease most of the current dry patches affecting sections of most southern parishes.   

The forecast is for the rains to start late April into May, and therefore the timeliness of these rains will ease the water stress currently affecting key agricultural areas, especially over southern parishes. Due to the variability in the start date of the rains we would advise that plans be made to reduce any possible impacts that could result from a delay in the start of the rains.
