El Niño is expected to influence global weather patterns, raising the risk of extreme heat and altering precipitation. In the U.S., wetter-than-average conditions are likely in the southern states during winter, while the northern states may experience drier conditions. The phenomenon could also reduce hurricane activity in the Atlantic but increase it in the eastern Pacific. Globally, El Niño may exacerbate droughts in some regions while causing flooding in others. The United Nations has issued a warning, emphasizing the urgent need for preparedness as El Niño could amplify the effects of climate change.
