A significant El Niño event, described by the Met Office as potentially the largest in living memory, is expected to disrupt global weather patterns. 

In the United Kingdom and north-west Europe, the phenomenon may lead to wetter and stormier conditions during the autumn and early winter, posing risks to transport and island communities. Conversely, forecasts for Canada suggest a milder and drier autumn, as the El Niño effect may shift storm tracks south and limit the movement of cold Arctic air. 

While regional impacts vary, the global event is expected to increase the risk of floods, droughts, and extreme heat through 2027.
