Currently, an unusually warm SSTA pattern persists across the central and east Atlantic tropics. The anomalous warm SSTA represents buoyant low-level atmosphere moisture. The IMME (model) forecasts the warm SSTA to surge westward into the northern coast of South America as a La Nina pattern (also) develops by October. The combination of the two SSTA regimes should yield a much-needed wet climate for Brazil.
