B.C. deluge could bring 250 mm of rain as forecasters predict flooding, landslides
Forecasters say the storm could trigger localized flooding and landslides as rivers rise rapidly and some roads become impassable.
Environment Canada issued orange rainfall warnings on Tuesday for Vancouver Island and the South Coast, forecasting up to 250 millimetres of rain and wind gusts reaching 110 km/h, with significant flooding and landslide risks.
Meteorologist Michael Gismondi attributed the heavy precipitation to atmospheric rivers, calling the drenching "fairly typical for this time of year." Warm temperatures through Wednesday may trigger snowmelt from shallow higher-terrain snowpacks, compounding flood risks.
Nearly 2,000 customers remain without power across Vancouver Island as crews work to restore service. The River Forecast Centre warned of peak flows expected Wednesday through Thursday, with localized flooding likely to make roads impassable.
A deadly weekend preceded the incoming storm: a driver was killed by a falling tree in Surrey, a pedestrian was struck in Vancouver, and a canoeist remains missing off northern Vancouver Island after disappearing Friday.
Rainfall is expected to ease Wednesday before a new system arrives Friday, potentially "re-intensifying" the precipitation. This incoming storm complicates recovery efforts as the region faces continued vulnerability to infrastructure damage and soil saturation.
