Early atmospheric changes associated with a developing El Niño event are beginning to appear in long-range weather forecasts, with meteorologists monitoring how the Pacific Ocean warming pattern could influence weather across the United States and Canada during the months ahead.

The report pointed to warming sea-surface temperatures in the equatorial Pacific and emerging shifts in air circulation that could become more pronounced through summer and into late 2026.
