Below is information provided by the BC River Forecast Centre on a Flood Watch for the BC Peace.
Peace Region, including tributaries around Fort St. John, Taylor, Chetwynd, Moberly Lake, Pine Pass, Hudson’s Hope and Dawson Creek
A low-pressure system is expected to set up across British Columbia on Friday, bringing the risk of heavy rainfall to the Peace Region. Rain is expected to begin falling on Friday afternoon and end by late Saturday.
There is still uncertainty of the location of the most intense rainfall, however there is relatively high confidence in the overall weather pattern. Environment and Climate Change Canada has issued a rainfall warning for the region, with 30 to 50 mm expected across the region, except near Hudson’s Hope and Chetwynd where 60 to 80 mm is expected. There will be an easterly flow to this pattern, with upslope conditions on the eastern slopes of the Rocky Mountains which may lead to higher rainfall amounts. Embedded convection and thunderstorms may also result in more localized higher rainfall amounts.
High streamflow is expected with the coming rainfall and active snowmelt runoff that is underway. Historically, rainfall events in the range of what is currently forecast have led to erosion and flood impacts through the region. Current hydrologic modelling is indicating the potential for 5-year to 10-year flows, and potentially higher, in areas around Hudson’s Hope, Moberly Lake, Chetwynd, Taylor, Chetwynd and Fort St. John. Given the current uncertainty in the storm track, it is possible that adjacent areas also receive heavy rainfall. Flows are expected to reach peak levels late Saturday and into Sunday.
The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high-streamflow period. Be prepared and know your hazards.
The River Forecast Centre continues to monitor the conditions and will provide updates as conditions warrant.
