Environment Canada has issued a warning about potential flooding in southwestern British Columbia over the upcoming weekend due to the convergence of high tides and strong winds. The weather agency highlighted the likelihood of moderate flooding resulting from “abnormal” high tides coinciding with a low-pressure weather system moving across the region. The statement emphasized that the South Coast is experiencing elevated astronomical tides as Earth nears perihelion, with falling atmospheric pressure expected to further raise coastal water levels beyond the expected tides.
The warning includes concerns about debris, erosion along coastal areas, and localized flooding. Meteorologist Ken Dosanjh from Environment Canada emphasized the importance of caution near the coastline. The statement covers the South Coast, as well as the western and eastern coastlines of Vancouver Island. The peak risk of flooding is anticipated on Sunday morning, with the unsettled weather pattern expected to persist from Saturday morning through Monday.
In addition to the flooding warning, Environment Canada issued a special weather statement cautioning about a period of freezing rain in the South Okanagan, Boundary, and West Kootenay areas on Saturday morning. The advisory includes the potential for freezing rain along Highway 3 from Paulson Summit to the Kootenay Pass. Avalanche forecaster Martina Halik of Avalanche Canada highlighted the anticipated elevated avalanche risks in the southern part of the province due to the storm activity.
Halik mentioned the formation of storm slabs and wind slabs, dense layers of snow rapidly accumulating over weak layers due to intense precipitation. She warned of the heightened dangers posed by the presence of a persistent weak layer in these conditions.
