The following Flood Watches and Advisories in the Southeast region are in effect as of Thursday May 24th, 0830hr:

  • Flood Watch – Slocan River
  • High Streamflow Advisory (DOWNGRADED) - Boundary , including the Kettle River, West Kettle River, Granby River and surrounding tributaries
  • High Streamflow Advisory  – West Kootenay, East Kootenay

Hot temperatures over the past few days have led to increased snow melt runoff throughout the region. In the Boundary, mid-elevation snow has dwindled and river levels rises in response to snow melt has been modest. River levels remain well below peak levels observed over the past two weeks. In the Kootenay, high elevation snow pack is still significant, with steady river rises over the past few days.

Temperatures are expected to remain high through the weekend. Flows are expected to continue to steadily, particularly in the Kootenay region; over the weekend flows may return to previously observed levels or possibly higher. In the Boundary, small rises are possible, but flows are expected to remain well below levels observed last week.

The River Forecast Centre will continue to monitor conditions and update this advisory as conditions warrant.
