Flood Warnings and Advisories

Flood Watch – Slocan River (DOWNGRADED), Boundary (DOWNGRADED)
High Streamflow Advisory – Kootenay (DOWNGRADED)
UPDATED: 10:30 May 22nd, 2018

The following Flood Warnings, Watches and Advisories in the Southeast region are in effect as of Tuesday May 22nd, 1030hr:

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

Rivers through the region have seen general improvement over the weekend, with moderate temperatures leading to decreased snow melt rates. In the Boundary, snow packs are becoming diminished leading to reduced flood risk from snow melt. In the Kootenay, rivers draining from higher elevation terrain still have enough snow to pose on-going risks from snow melt runoff.

Temperatures are expected to remain high through Thursday of this week. Flows are expected to steadily rise through the week, particularly in the Kootenay region; by later in the week 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.
