As of 8:30am, Monday, November 15, the River Forecast Centre is upgrading to a Flood Watch for the Sea to Sky.
The public is advised stay clear of fast-flowing rivers and potentially unstable riverbanks during the high-streamflow period.
A significant atmospheric river has made landfall across southern coastal regions of British Columbia. Observed rainfall amounts since yesterday have been in the 100-140mm range through Howe Sound, North Shore Mountains, and Sunshine Coast; 90-160mm in the Fraser Valley – East, Fraser Canyon and areas around Hope and Harrison Lake.
Environment and Climate Change Canada have continued rainfall warnings in effect across the region. Rainfall is expected to taper off by Monday afternoon, with additional amounts of around 50mm expected through the eastern Fraser Valley, and 30-40mm in other areas.
Temperatures have been rising, with temperatures in the 5-7°C range being observed at automated snow weather stations across the region. Snowmelt is being observed at mid-elevations and is expected to add additional runoff to rivers.
Rivers through the region are expected to remain high through Monday morning, with improvements expected Monday afternoon as rainfall eases.
The River Forecast Centre continues to monitor the conditions and will provide updates as conditions warrant.
