Rising Risk of 'Super' El Niño to Impact North America
Rising Risk of 'Super' El Niño to Impact North America
US · Published Jun 23, 2026
The US National Oceanic and Atmospheric Administration (NOAA) has announced that El Niño, a Pacific weather pattern known for raising global temperatures, has begun and is expected to intensify throughout
El Niño occurs due to variations in Pacific Ocean temperatures and easterly winds, disrupting weather patterns worldwide. This phenomenon is expected to bring wetter and stormier conditions to the southern United States while causing drier and hotter weather in northern regions, including Canada. The Pacific jet stream is anticipated to shift southward, leading to reduced snowfall in the northern Rockies and drier conditions in the Pacific Northwest. Additionally, the Atlantic hurricane season, which runs from June to November, is likely to be quieter than usual due to El Niño's influence.

Impact & Risks

The effects of a strong El Niño will be felt across North America, with significant regional variations. Southern states may experience increased rainfall and storm activity, potentially leading to localized flooding. Conversely, northern states and Canada are expected to face hotter and drier conditions, which could exacerbate drought risks and reduce snowfall in mountainous areas like the northern Rockies. These changes may also impact agriculture, water resources, and wildfire risks in affected regions. The quieter Atlantic hurricane season could reduce the immediate threat of tropical storms, but other weather-related challenges remain significant.
