Flood Warnings and Advisories

Flood Watch – Central Coast (MAINTAINED)

ISSUED: 1:45 PM October 29, 2020

The River Forecast Centre is maintaining a Flood Watch for:

  • Central Coast including Bella Coola River and tributaries, Kingcome River, Owikeeno/Rivers Inlet and surrounding areas

A series of rainfall events are impacting the Central Coast. Rainfall totals since Tuesday have been in the 75-175mm range throughout the region. A lull in rainfall rates overnight has led to some easing of river rises, particularly in smaller tributary rivers, however larger rivers, including the Bella Coola River, Wannock River and Owikeeno Lake and Kingcome River, remain high. Additional moderate rainfall is expected through Thursday and into Friday, with an additional 20-50 mm or more of precipitation being forecasted. Rivers are expected to remain high as this additional rain falls and works through the river systems. Rises in rivers above current levels is possible on the Bella Coola River and Kingcome River, and likely to occur on Owikeeno Lake and the Wannock River. Once rainfall has eased on Friday, river conditions are expected to stabilize into the weekend.

The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high-streamflow period.

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