Brief Summary: The forecast for the next three month is for warmer than normal temperatures with above normal rainfall likely over sections of eastern and central parishes. The latest forecast from the computer models are indicating a probability of near normal to above normal rainfall activity across most stations. Rainfall activities are not likely to have significant declines in amounts, even as scientists continue to monitor the sea surface temperatures over the eastern Pacific for El Ni  ño development in the coming months.

Over the past three months (March, April and May) the island recorded significant increases in rainfall amounts, which offset the deficit in rainfall that was observed over most central and western parishes during period of December through to February.
