Environment and Climate Change Canada has announced that an atmospheric river is set to impact British Columbia’s south coast this weekend. Heavy rain is already affecting the north coast, and conditions are expected to worsen.
Metro Vancouver should prepare for the heaviest rainfall by Sunday, with forecasts predicting between 75 and 125 mm. Areas like the North Shore Mountains could see even more. This could lead to water pooling on roads and possible landslides in steep or deforested areas, so drivers should be cautious and expect delays.
Along the north coast, up to 100 mm of rain is anticipated, adding pressure to an already saturated region. Another weather front will roll in on Sunday, bringing even more rain and posing risks for power outages.
The Ministry of Water, Land, and Resource Stewardship has issued a flood watch for areas including north and west Vancouver Island, the Sunshine Coast, and Howe Sound. The ministry emphasizes that prolonged rain and warmer temperatures could lead to significant snowmelt, especially in mid-elevation areas.
In fact, climate scientists now see atmospheric rivers as a growing concern. After the major floods in 2021, they warn that these extreme weather events could become routine. Infrastructure improvements are vital to help mitigate future impacts.
High streamflow advisories are also in effect for various regions, warning of potential road washouts, localized flooding, and landslides. Authorities advise keeping away from riverbanks and checking road conditions before traveling.
As weather patterns shift, it’s crucial to remain vigilant. The combination of heavy rainfall and rising temperatures could escalate flood hazards, making awareness and preparation essential for all residents.
