Brief Summary: Through the period of June to August the computer models are indicating near to above normal in rainfall amount across most areas. As we transition through the first three months of the hurricane season, rainfall activities seems likely to be near normal to above normal due to several environmental and local factors.  

The forecast for June and July remains near normal, however as we approach the month of August the models indicates an increase in rainfall amounts. Although we are predicting a slight decline in rainfall especially for July the impact on agricultural areas, especially over southern parishes are not expected to be significant. However, we will continue to monitor the model outputs in order to advise our farming communities should the situation change and warrant action on their part. Temperature predictions remain above normal; and so far above normal temperatures have been realised in some sections of the island. This could be a very problematic for farming interests as it places additional stress on crops.
