The BC River Forecast Centre has issued a High Streamflow Advisory for Southern Vancouver Island including the Cowichan, Koksilah, and Chemainus Rivers. Rainfall of 100-150mm is likely between Tuesday and Thursday and warm temperatures could lead to snowmelt. River levels are expected to peak Wednesday or Thursday at levels similar to those experienced last weekend.
A High Streamflow Advisory means that river levels are rising or expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas (e.g. Cowichan Bay Road) is possible.
