January Drought Forecast Map


Brief Summary:  Over the next three months the most stations that were examined could receive near normal to above normal rainfall based on the latest outlook from the computer models. Although some areas especially, over eastern parishes are likely to experience below normal rainfall the concerns for drought impact remains low as we are still in the rainy season.  

The forecast for November to January indicates moderate chance of increased rainfall amounts as environmental conditions remain favourable. Rainfall amounts over the next three months are likely to remain near normal to above normal thus significantly reducing the likelihood of drought concerns at this time.
