El Niño's impacts are expected to vary globally. In the U.S., the Northwest, northern Plains, and Upper Midwest may experience drier and warmer conditions, exacerbating drought and wildfire risks. Conversely, the Gulf Coast and Southeast could see increased rainfall, potentially alleviating drought. California may face wetter conditions, with a higher likelihood of atmospheric rivers and heavy snowfall in the mountains. Hawaii could see a mix of increased summer rainfall followed by drier conditions, raising wildfire risks. Globally, El Niño could intensify heat waves, droughts, and heavy rainfall events, particularly in vulnerable regions. The Pacific hurricane season is expected to be more active, while the Atlantic hurricane season may see reduced activity due to increased upper-level winds.
