Flood Warnings and Advisories
Flood Watch – West Kootenay (UPGRADED), Boundary (MAINTAINED)
High Streamflow Advisory – East Kootenay
ISSUED: 12:45 PM May 30, 2020
The River Forecast Centre is upgrading to, or maintaining, a Flood Watch for:
- West Kootenay including the Slocan River, Salmo River and surrounding tributaries (UPGRADED)
- Boundary Region including the Kettle River, West Kettle River, Granby River and tributaries
The River Forecast Centre is maintaining a High Streamflow Advisory for:
- East Kootenay including the Moyie River and surrounding tributaries
River levels have remained elevated due to on-going snowmelt and episodes of precipitation. Some rivers have experienced more rapid rises earlier in the week in response to rainfall last weekend and through the early part of the week.
A high-pressure system is moving out of BC, and temperatures expected to remain high on Saturday. In areas with some mid-elevation snowpack remaining, rivers levels may see additional rises from snowmelt today; this includes the West Kettle, Kettle and Granby Rivers. In areas with higher elevation terrain, on-going rises in river levels are expected due to accelerated snowmelt. This includes the Slocan River, Salmo River, Moyie River and surrounding tributaries.
Following this hot spell, weather is expected to transition to a low-pressure trough and cold front. This brings the potential for thundershowers ahead of the trough on Saturday evening, transitioning to more organized rainfall overnight Saturday and into Sunday. Exact amounts of rainfall and locations of highest rainfall amounts is still uncertain, however current weather modelling is indicating the potential for moderate to high rainfall amounts (as low as 5-15mm to as high as 30-40+mm) exists throughout the region over this time frame. Current weather modelling is indicating the risks of highest rainfall amounts are around the Boundary and West Kootenay region, however risks of high rainfall amounts are present throughout the region. If high rainfall amounts materialize, flood conditions are likely to occur, particularly in areas that already have elevated river levels.
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 situation and provides updates as conditions warrant.
