Flood Warnings and Advisories
The River Forecast Centre is issuing a High Streamflow Advisory for areas in the South Interior including:
- Boundary Region, including Grand Forks
- West Kootenay, including tributaries into Arrow Lakes, Slocan Lake and Kootenay Lake
- East Kootenay, including the Elk Valley near Fernie
A frontal system is approaching the South Interior this evening (April 9). It’s expected to stall over the Kootenay region on Monday (April 10) and bring basin-wide, prolonged rainfall until Tuesday morning (April 11). Rainfall amounts are forecast to reach 30 to 50 mm across the regions. Freezing levels are expected to rise between 2,000 to 2,500 metres.
Seasonal to below seasonal temperatures and dry conditions have persisted through late winter and early spring. River flows in the Kootenay region are currently below normal as the freshet snowmelt season has yet to significantly begin. The upcoming heavy rainfall is expected to cause flashy rises in creeks and rivers in the region. Smaller, low elevation creeks with remaining snowpack are most at risk. These rain-on-snow events have a high amount of uncertainty based on rainfall totals, ripeness of the snowpack to melt and the fluctuation of the freezing level.
Conditions are expected to be dynamic throughout the weekend with periods of rapid river rises. Fast-flowing rivers pose increased risk to life safety.
