Metro Vancouver weather forecast heading into December
In a recent update, the National Oceanic and Atmospheric Administration (NOAA) called for a 75 per cent chance that La Niña will be present this winter and won't change to a "neutral" weather pattern until about February.
Typically, La Niña's impact on southern B.C. doesn't start to show until the late fall or early winter. But it does tend to produce cooler than normal conditions and snowier conditions over the mountains.
Environment Canada will release its official winter forecast on Dec. 1.
