The United Nations' meteorological agency states that the El Nino phenomenon is expected to return as early as May, leading to increased rainfall and global droughts.
Northern region heatwaves may appear early, last longer, and be more intense than multi-year averages; the central region's rainy season may arrive late and end early, with drought risk.
North American and European meteorological agencies warn of the risk of the strongest super El Nino in history, redrawing the global weather map and pushing Earth to record high temperatures.
