The River Forecast Centre is ending the High Streamflow Advisory for:

  • The Upper Fraser River including tributaries above Hansard
  • The mainstream of Middle Fraser River to Lytton

The rivers have responded to the thunderstorms yesterday and this morning and the river levels have risen slightly. According to the latest hydrological modeling, the river levels are expected to rise slightly but below the 2-year return period levels this weekend. With the forecast seasonably hot and dry weather pattern beginning Saturday, the river levels are expected to drop further next week.

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