The River Forecast Centre is issuing a High Streamflow Advisory for North Shore, Metro Vancouver, Fraser Valley and surrounding areas.
The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high-streamflow period.
A major weather pattern shift will occur this weekend, with the arctic outflow switching to moist, mild weather systems.
A moderate amount of rain, 50-100 mm, is expected over western-facing slopes of Vancouver Island and the Lower Mainland.
Lower elevation creeks and rivers are most at risk, especially where recent coastal snowfall may create a flashier rain-on-snow event.
River levels are expected to rise quickly in response to this storm, with high flows expected Sunday through Monday.
