July Drought Forecast Map


Brief Summary:  As we look at the upcoming three months, there will be a noticeable shift in the environmental conditions. Scientists are predicting that over the coming months a shift towards warmer than normal sea surface temperatures over the eastern Pacific could see a weak El Ni ño forming.

This phenomenon could impact climatic and weather conditions across Jamaica, resulting in warmer than normal temperatures as well as reduced rainfall activity. The latest forecast from the computer models are indicating a probability of below normal to near normal rainfall activity across most stations.
