A high streamflow advisory is now in effect for the areas around Nanaimo, Duncan and the Cowichan Valley, and the Sunshine Coast from Howe Sound to Powell River.
The BC River Forcast Centre says another strong Pacific storm with warmer temperatures is expected to bring moderate to heavy rain to Vancouver Island and the South Coast beginning Tuesday morning.
Higher freezing levels in the mountains will increase rainfall and snowmelt at low to mid elevations, particularly for Vancouver Island.
The rain will likely be more intense, falling in a relatively short period of time.
Rivers are expected to rise rapidly on Tuesday, with a potential for higher peak flows.
Localized flooding is possible, particularly at lower elevations and areas with poor drainage.
