More heavy rain to arrive in B.C. overnight amid atmospheric river

The atmospheric river that’s brought heavy precipitation to the West Coast through the holiday weekend will continue into the final week of the year.

B.C.’s soggy pattern will continue through the final week of the year as several additional moisture-laden systems take aim at the province through the first half of the week.

Heavy rain will pick up during the overnight hours Monday as a low-pressure system pushes into the province from south of the border. Steady rainfall—heavy at times—will continue through Tuesday night.

Another, thankfully lighter round of rain will sweep into the West Coast late Wednesday evening, lasting into Thursday.

The latest forecast for additional rainfall through Wednesday calls for 30-50 mm across the Lower Mainland, with higher totals north of Metro Vancouver and across portions of Vancouver Island.

Between the rain that’s fallen in recent days and the rain that’s yet to come, Vancouver could rack up more than 100 mm of rain by the middle of the week.

Localized ponding on streets and parking lots remains a hazard anywhere snow still clogs storm drains.

Environment and Climate Change Canada (ECCC) issued rain warnings for Metro Vancouver and parts of Vancouver Island into Tuesday. "A long episode of rain, at times heavy, is expected. The frozen ground has a reduced ability to absorb this rainfall," states ECCC.

After a strech of weather that has made travel in B.C. quite difficult, ECCC warns drivers to be aware of flooding and to avoid driving through water on roads.

Cooler air away from the coast will bring steady snow to B.C.’s Interior over the next couple of days.

Forecasters expect B.C.’s soggy and unsettled pattern to continue into the beginning of the new year.
