High Streamflow Advisory – Upper Columbia (NEW)
ISSUED: 12:30 PM July 1, 2020

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

  • Upper Columbia

Over the past 24-hours, the Upper Columbia has received 5 to 20 mm of precipitation at high elevation automated snow weather stations. A further 30 to 50 mm of precipitation is possible through Friday. Today’s CLEVER model run has forecasts for the Upper Columbia rivers reaching 5-year to 20-year flows in response to the wet weather.

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.

A Flood Watch means that river levels are rising and will approach or may exceed bankfull.  Flooding of areas adjacent to affected rivers may occur.
A Flood Warning means that river levels have exceeded bankfull or will exceed bankfull imminently, and that flooding of areas adjacent to the rivers affected will result. 

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