The warning, which anticipates accumulation of up to 80 millimetres of rain by Tuesday, applies to the North Shore, northeast parts of Metro Vancouver — including Coquitlam and Maple Ridge — and the western Fraser Valley.

Metro Vancouver’s southwest, which includes Richmond and Delta is also facing a wind warning, with winds of up to 70 kilometres per hour forecast for Monday.

What’s more, the storm is forecast to arrive during a king tide — a period when natural forces produce the highest tides of the year.

The combination of king tides and stormy weather has been known to create limited flooding in low-lying areas.

“The strong southerly winds will coincide with high tides and may produce higher than normal water levels (storm surge) for areas near the shore,” reads the warning.

The rest of Metro Vancouver remains under a special weather statement, with strong winds and rain anticipated Sunday and into Monday morning and the possibility of thunderstorms on Tuesday.

The Lower Mainland isn’t the only part of the coast forecast to get battered.

Motorists headed inland on the Coquihalla are being advised that freezing rain is possible overnight and into the morning.

“Increasing southwesterly winds will lead to the development of a layer of warm air aloft which could melt falling snow. Should surface temperatures dip much below zero tonight, higher elevations of the Coquihalla could see a significant period of freezing rain begin before morning,” states Environment Canada.
