High Streamflow Advisory

The River Forecast Centre has issued a High Streamflow Advisory for the Fraser Valley.

A High Streamflow Advisory means that river levels are rising or expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas is possible.

A moderate atmospheric river event is currently impacting southern Vancouver Island, the Fraser Valley and surrounding areas. Rainfall amounts in the 25-40 mm range have been observed this morning, with Environment and Climate Change Canada forecasting additional amounts in the 30-60 mm range for areas around Metro Vancouver and the Fraser Valley for the remainder of the storm today.

Rivers are expected to rise rapidly through Thursday in response to rainfall, with peak flows expected later Thursday or into Friday for larger rivers, including the Chilliwack River. 

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

Get your home flood ready:

• Store valuables and important items or documents in water-tight containers or in high places, like on a tall shelf or upper floor.
• Clear gutters
• Keep nearby storm drains clear of debris
• Direct downspouts away from basements

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