An intense Pacific frontal system impacted south-west British Columbia over the past two days, bringing heavy rainfall across the region. Rainfall amounts in the 200-300+ mm range were observed on West Vancouver Island, and 60-150+ mm in Central Vancouver Island, Eastern Vancouver Island, Southern Vancouver Island, Howe Sound and the Lower Mainland.
Rivers have responded to this rainfall, with many real-time Water Survey of Canada hydrometric gauges on Vancouver Island reaching 2-year to 20-year return period flows. For most areas, peak flows have occurred and river levels are now receding. High flows persist in areas of central, eastern and southern Vancouver Island, including the Sproat River, Stamp River, Somass River, Millstone River, Nanaimo River, Cowichan River, Englishman River, and Little Qualicum River. Elevated flows in these regions are expected to continue through Friday; however, significant additional rises are not expected at this time. River levels are expected to continue to improve into the weekend.
The River Forecast Centre will continue to monitor conditions and update this advisory as conditions warrant.
