Natasha Ramsahai, a meteorologist with CityNews Winnipeg, warned that a robust El Niño pattern could influence temperature and precipitation across Canada during the winter of 2026‑2027 and into the spring of 2027. She explained that the phenomenon, driven by unusually warm waters in the Pacific Ocean, has the capacity to modify atmospheric circulation and thereby affect weather conditions over a broad swath of the country.
Ramsahai noted that the warm Pacific surface temperatures associated with El Niño tend to shift jet stream patterns, which can lead to milder air masses moving into parts of Canada. This shift may result in above‑average temperatures in regions that typically experience harsher winter cold. At the same time, the altered circulation can change where moisture is deposited, potentially creating different rainfall or snowfall patterns than those seen in a neutral or La Niña year.
The meteorologist highlighted that while El Niño is a recurring climate event, its intensity varies from cycle to cycle. The current outlook points to a particularly strong episode, which could bring notable departures from typical winter weather. Residents in areas that usually receive heavy snow may see reduced snowfall, while other locales could experience increased rain events, especially as the season transitions into spring.
Ramsahai emphasized that the influence of El Niño does not affect all of Canada uniformly. Some regions may continue to see cold spells despite the overall trend toward milder conditions. The variability underscores the importance of monitoring the evolving pattern throughout the season.
She concluded by reminding viewers that the El Niño-driven changes are part of a larger climatic system and that forecasting will continue to incorporate the latest observations as the winter progresses into the coming months.
