A very strong El Niño could lead to significant weather disruptions globally. In the U.S., warmer-than-average winter temperatures are expected in the northern regions, while the southern states may experience cooler and wetter conditions. The event could also suppress Atlantic hurricane activity while intensifying storms in the Eastern Pacific. Globally, El Niño is likely to contribute to higher average temperatures, potentially challenging existing global heat records. However, NOAA cautions that the impacts of El Niño are not uniform and may vary by region and season. (Source: ABC News, Source time: not specified)
