Scientist warns of potential impacts of super El Niño on Greater Victoria
Scientists say the event could also deepen wildfire, flooding and water-supply risks as ocean temperatures rise and snowpack declines.
The World Meteorological Organization announced on June 2 an 80 per cent likelihood of a strong El Niño event from June to August this year, with scientists warning it will bring milder winter temperatures to Greater Victoria.
El Niño shifts global wind patterns, deepening the Aleutian Low near Alaska and pushing the jet stream northward, which creates milder winter temperatures across Canada, according to William Merryfield of Environment and Climate Change Canada.
Warmer temperatures risk early snowpack melt and increased wildfire threats, while coastal areas face flooding as sea levels rise around 20 centimetres above normal tidal levels, Merryfield said.
Greater Victoria should manage water supplies and conservation efforts going into next year, as reduced snowpack can affect stream and river runoff, creating dry conditions on land.
This event arrives as Canada's winters are already warmer than 40 years ago, and 2026 is projected to be one of the hottest years on record, intensifying climate pressures.
