Environment Canada has issued a special weather alert for British Columbia this weekend.
Starting early Saturday morning and continuing until midday Sunday, a tropical "atmospheric river" is expected to deliver heavy rain, mild air, and some strong winds to much of the central and southern B.C. coast.
Northern Vancouver Island and the Central Coast will be the most affected, according to the government bulletin, and the largest amount of rainfall is predicted for the west coast of Vancouver Island and the Central Coast's communities. Up to 100 millimetres may fall in those areas.
The alert also notes that strong winds gusting up to as much as 90 kilometres per hour will blast those same areas Saturday morning, potentially as far as the North Coast.
Parts of Metro Vancouver—especially mountainous areas like the North Shore and the northeast of the region, including Coquitlam and Maple Ridge—are warned to expect in excess of 50 millimetres of rain in 24 hours, as is Howe Sound and the Sunshine Coast.
High runoff and rising river levels are expected throughout the region.
