- El Niño shifts winter odds towards wetter southern US conditions.
- Northern US and Canada may be warmer and drier.
- Forecast impacts are possible, not certain.

## Summary

A developing El Niño, described as exceptionally strong by some measures, could influence winter weather across the US and Canada in 2026–2027. It shifts the odds towards warmer, drier conditions in many northern areas and wetter weather in parts of the south, but outcomes vary and are not guaranteed.

The Pacific jet stream may steer rain-bearing systems across the southern US, raising flood risks in the south-east and California; wildfire-scarred areas may be especially vulnerable to flooding and mudslides. Northern regions, including western and central Canada, are more likely to have mild, dry weather, which can mean less snow and increased drought or wildfire risk later. El Niño can also favour heavy mountain snowfall in the southern Rockies and California, while ocean waves may raise coastal sea levels by 15cm or more.
