High Streamflow Advisory issued for Howe Sound

The River Forecast Centre has issued a High Streamflow Advisory for the South Coast including tributaries around Squamish and Howe Sound. 

A series of storms is passing over British Columbia with the next storm expected to begin impacting coastal areas late Monday and overnight into Tuesday.

This is forecast to bring moderate to heavy rainfall amounts across Vancouver Island and the South Coast. Environment and Climate Change Canada has issued rainfall warnings for areas, with rainfall amounts in the 50-60 mm range anticipated in the Howe Sound and Metro Vancouver areas, and potentially higher over higher terrain and in exposed coastal areas on Vancouver Island. Along with moderate to heavy rain, temperatures are expected to rise, with freezing levels forecast to reach above 2000m. This may contribute additional runoff from rain-on-snow and snowmelt.

River levels are expected to rise in response to this storm, with high flows expected overnight on Monday and through Tuesday. Prolonged wet weather over the past one to two weeks has led to ground saturation in some areas, and this may contribute to increased flows in response to this rainfall.

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 will provide updates as conditions warrant.
