Environment Canada warns of heavy rain, wind and snow across parts of B.C. as atmospheric river approaches

Environment Canada says parts of British Columbia are expected to see heavy rain, strong winds and periods of snow this week as an atmospheric river approaches the coast.

The federal forecaster says Metro Vancouver, the Sunshine Coast and Howe Sound could receive up to 150 millimetres of rain by Wednesday, with prolonged heavy rainfall forecast to begin early this week. According to Environment Canada weather warnings, some areas could also see rain mixed with snow, raising concerns about rising river levels and localized flooding.

Environment Canada has issued yellow weather warnings indicating the system could cause extensive pooling on roads and increase the risk of landslides in some areas.

Forecasters say parts of the central coast and sections of Vancouver Island may also experience blustery winds, with gusts reaching up to 110 kilometres per hour through Tuesday night. Snow levels are expected to fluctuate significantly as the system moves through the region.

A winter storm warning covering the north coast between Kitimat and Terrace says up to 30 centimetres of snow could fall before conditions change to rain. The warning says the area could receive up to 80 millimetres of rain after the snowfall ends, with power outages and property damage considered likely.

The B.C. River Forecast Centre issued high streamflow advisories on Friday for Vancouver Island and parts of the north, south and central coast ahead of the weather system.
