An intense Pacific frontal system has stalled over south-west British Columbia, bringing heavy rainfall across the region. Rainfall amounts exceeding 150mm have been observed since yesterday on West Vancouver Island, and 60-100+ mm in Central Vancouver Island, Eastern Vancouver Island, Howe Sound and Lower Mainland.
Streamflow has been rising rapidly in response to this rainfall, with areas on Vancouver Island currently reaching or exceeding 2-year return period flows. The Little Qualicum River near Qualicum Beach (Water Survey of Canada gauge 08HB029) is currently flowing at approximately 210 m3/s (20-year flow).
Additional rises are possible later on Wednesday. For larger and lake-influenced systems, including the Cowichan River and Somass River, rises are expected into Thursday. 
The River Forecast Centre will continue to monitor conditions and update this advisory as conditions warrant.
