The most impacted regions will be the North Shore and Metro Vancouver.
“It is expected that rivers will reach or exceed 5-year flows, including the Coquitlam River and Alouette River,” said the BC River Forecast Centre.
“While some snowmelt is expected during this event, snowpack at higher elevations is deep enough that it will provide some absorption of the added rainfall and buffer the impact of the rainfall on runoff.”
The public is advised to stay clear of fast-flowing rivers and riverbanks during the high-river-level period.
According to Environment Canada, total precipitation amounts are expected to be between 60 to 120 mm for the Fraser Valley, 130 mm (13 cm) for Howe Sound, and 100 to 120 mm (between 10 to 12 cm) for Metro Vancouver.
