B.C. Gets Hammered on Multiple Fronts
British Columbia is dealing with a broad and intense weather event this week, with dozens of Environment Canada alerts in effect across the province. Rain, snow, winter storms, and flood watches are hitting different regions simultaneously, a reminder that spring in B.C. can be anything but gentle.
South Coast and Metro Vancouver: Up to 120mm of Rain
The Lower Mainland is bracing for a powerful atmospheric river, a long, narrow band of moisture-laden air that can deliver extraordinary amounts of rain in a short period.
Environment Canada is forecasting up to 120mm of rain for northeast Metro Vancouver and the North Shore. "Extensive water pooling on roads and washouts may occur," the agency warned, with risks of landslides in vulnerable hillside areas.
Vancouver Island: Even Wetter
Vancouver Island is facing some of the most extreme rainfall totals in this event, with up to 150mm forecast for the north and west coasts, and some areas potentially receiving 200mm or more.
The situation is serious enough that B.C.'s River Forecast Centre has upgraded high streamflow advisories to flood watches for northern and western Vancouver Island and the Central Coast. Communities along flood-prone rivers should be monitoring conditions closely.
Sea-to-Sky: Winter Storm Warning
From Squamish to Whistler, a winter storm warning is in effect with up to 20cm of snow expected by Monday midday, followed by heavy rain of up to 70mm, a combination that creates particularly hazardous conditions on the Sea-to-Sky Highway, already one of the most challenging mountain routes in North America.
Northern B.C.: Already Buried
Kitimat and Terrace have already received up to 40cm of snow since Sunday. A winter storm warning remains active for Bella Coola and Hagensborg on the Central Coast, where 15cm of snow is expected to transition to heavy rain, a cycle that can be especially damaging to structures and roads.
Avalanche Risk Elevated
Avalanche Canada has rated the risk as high (level 4 of 5) for the Sea-to-Sky, South Coast, and most northern mountain terrain. Anyone planning backcountry activities in these areas should postpone until conditions improve.
Ottawa's Take on B.C. Weather
For Ottawa residents with family or travel plans in British Columbia, this is a significant weather event worth monitoring. Check DriveBC and Environment Canada's weather alerts before heading out on mountain roads, and make sure loved ones in affected areas are prepared.
