Impact & Risks

The intensifying El Niño could lead to significant global weather disruptions. NOAA and WMO warn of potential changes in rainfall and temperature patterns, increasing risks of floods, droughts, and extreme heat. AccuWeather forecasts an active southern storm track in the U.S., above-average temperatures in northern regions, and persistent drought conditions in parts of the West.

The Atlantic hurricane season may see reduced storm activity due to increased wind shear, while the Pacific basin remains active.
