Heavy rain, mountain snow expected across Metro Vancouver as strong system moves in

Environment Canada is warning residents across parts of Metro Vancouver to prepare for heavy rain and snowfall at higher elevations as a strong weather system moves into the region starting Monday night.

According to a special weather statement, some areas near the North Shore mountains could receive close to 70 millimetres of rain, while the City of Vancouver may see totals of up to 40 millimetres by Tuesday afternoon. The heaviest rainfall is expected along mountain slopes, where moisture from the frontal system is forecast to intensify.

Forecasters say colder air will cause precipitation to fall as snow at higher elevations. As the snowline lowers, areas such as Burnaby Mountain and sections of the Upper Levels Highway on the North Shore could see several centimetres of accumulation. Environment Canada also warns of significant snowfall amounts in the North Shore mountains.

The weather statement covers the northern half of Metro Vancouver north of the Fraser River, including communities such as Coquitlam, New Westminster and Maple Ridge. Drivers and commuters are being urged to use caution, particularly on elevated routes where winter conditions may develop quickly.
