ISSUED: 12:00PM August 21, 2020

The River Forecast Centre is issuing a High Streamflow Advisory for:

  • The Liard River (and tributaries)
  • The Muskwa River (and tributaries)

A significant low-pressure system is approaching northeast B.C.  Environment and Climate Change Canada have issued a Rainfall Warning for the Fort Nelson and Muncho Lake Park regions.  They are forecasting rainfall amounts of 40 to 75 for tonight through Saturday with the higher amounts expected near the eastern slopes of the Rockies.
The River Forecast Centre’s CLEVER model is forecasting the possibility of flows reaching above 5-year return period levels in the region, including the Liard River, Muskwa River and tributaries.  Smaller watersheds are expected to peak late Saturday or Sunday, whereas larger systems will likely reach peak flows early next week.

The River Forecast Centre continues to monitor the conditions and provides updates as conditions warrant.
