Strong 'Super El Niño' Expected to Impact U.S. Snowfall Patterns
Strong 'Super El Niño' Expected to Impact U.S. Snowfall Patterns
US · Published Sep 8, 2026
A rapidly intensifying 'super' El Niño is poised to significantly influence weather patterns across the United States this winter.
According to NOAA, sea-surface temperature anomalies in the eastern equatorial Pacific have exceeded 2°C, with the July Niño-3.4 index 1.4°C above normal.

Impact & Risks

The southern U.S., particularly states like California, Nevada, Utah, Colorado, New Mexico, and Arizona, could see above-average snowfall in higher elevations, which is critical for water supplies and drought mitigation. Conversely, warmer temperatures in the northern U.S. may limit snowfall, impacting regions such as the Pacific Northwest and Upper Midwest. While El Niño increases the likelihood of wetter conditions in the southern tier, precipitation may fall as rain or sleet instead of snow, depending on temperatures. This variability underscores the importance of elevation and storm track in determining snowfall outcomes.
