Heavy rainfall warning issued: typhoon remnants to pummel Metro Vancouver all week

Dec 19 2017, 8:24 pm

Keep your umbrella close to you at all times and postpone any outdoor excursions, it’s about to get incredibly wet in Metro Vancouver.

Environment Canada has declared a heavy rainfall warning for Metro Vancouver. Windy conditions and up to 50 mm is in the forecast for the region beginning Monday afternoon and easing off by Tuesday morning. Rainfall will be heaviest near the North Shore Mountains.

However, it is only the first of a series of consecutive powerful Pacific frontal systems expected to hit the South Coast this week.

The remnants of Typhoon Phanfone, a deadly tropical cyclone that hit Japan last week, merged with a low pressure system from the Gulf of Alaska are responsible for this week’s forecasts of stormy weather in southern B.C. The moisture-rich remnants of the typhoon are being carried through the jet stream, which has taken a trajectory over the Metro Vancouver region.

A weak high pressure system could bring a short temporary break from rain or even periods of sunshine on Tuesday, but another storm-force system is expected to arrive later in the evening or early Wednesday morning.

The mid-week storm will bring more heavy rains and strong winds to the South Coast. In addition, freezing levels are expected to drop and lead to some snow accumulation at the upper elevations of Whistler and Blackcomb mountains.

Persisting similar conditions in the Pacific might also cause the remnants of Typhoon Vongfong to strike the South Coast after the set of systems from Phanfone passes through.
