Rainfall warning issued for Vancouver, flurries possible in Lower Mainland

Southern areas of B.C. will see rain and snow due to the parade of low pressure systems tracking through the region. Higher elevation areas, including Whistler, are set to see heavy snow and many of these regions will receive 15-20 cm by Wednesday evening. Regions with elevations near sea level will see rain that can be heavy at times. Western Vancouver Island will see the heaviest rain and accumulations could exceed 100 mm. Details and timing, below.

WEATHER HIGHLIGHTS:

  • Alpine snow on Wednesday could range between 15-20 cm

  • Next low pressure system makes its way to B.C. to welcome in the New Year

WEDNESDAY: STRONG WINDS, HEAVY RAIN, MOUNTAIN SNOW

Rain will continue for the Lower Mainland and Vancouver Island for most of Wednesday. Environment Canada has issued a rainfall warning for Metro Vancouver and says that over 50 mm of rain is possible through the day.

Some higher elevation regions are seeing the potential for a very light amount of snow. “There might be the chance for some flurries for areas above 100 metres, so Simon Fraser University might even get a dusting of snow,” says The Weather Network meteorologist Matt Grinter.

West Vancouver Island is expected to see 100 mm through Wednesday afternoon and Environment Canada warns that localized flooding in low-lying areas is possible. There could be some snow at sea level in parts of eastern Vancouver Island in the morning, but not much accumulation is expected since most of the snow will remain inland at the high elevations.

Travel through the mountain passes could be difficult on Wednesday, as there will likely be significant snow accumulation between 15 to 20 cm. The likeliest snowfall accumulation will be in regions that are above 200 metres.

The avalanche threat will increase as a result of the fresh accumulating snow adding to snowpack. Most mountain passes will see considerable or high risk ratings.

The system will likely move out of the region by the overnight hours, allowing for a bit of a break before the next Pacific system welcomes the new year in B.C.

LOOK AHEAD: ACTIVE PATTERN CONTINUES

The active pattern will continues for the South Coast with a parade of systems. Seven-day rain totals of 75-150 mm are expected for the region, with 50-75 mm for Victoria, and 150-300 mm for the western Vancouver Island. As well, there will be 1-2 metres of snow for the alpine regions including the ski areas.

Another round of heavy precipitation is expected this weekend, with the potential for two rounds of significant snow for the southern Interior. The unsettled pattern will continue well into next week.

Temperatures will be near to slightly below seasonal for coastal areas and near seasonal for the Interior and areas east. No sustained Arctic air is in sight.
