Flood Warnings and Advisories
Central Region - High Streamflow Advisory (MAINTAINED) – North Thompson Tributaries, North Okanagan, Nicola River, Salmon River (Salmon Arm)
ISSUED: 2:30 PM May 19, 2020
The River Forecast Centre is maintaining a High Streamflow Advisory for:
- Tributaries of the North Thompson River around Clearwater and Barriere
- Nicola River including Upper Nicola River above Nicola Lake and downstream through Spences Bridge
- North Okanagan including tributaries around Vernon, Lumby and Winfield
- Salmon River near Salmon Arm
Wide-spread precipitation throughout the region was observed Sunday and Monday, with rainfall amounts in the 15-25mm range being observed in most areas. This rainfall has led to rapid rises in river levels on Monday and into Tuesday in some areas. River levels have generally reached peak levels from runoff from this rainfall event, except in areas of the Upper Nicola River where flows continue to rise.
River levels are expected to remain elevated over this week with on-going melt of snow pack in contributing watersheds. Over this period, rivers are sensitive to additional rises from rainfall. Unsettled weather is expected through this week, with current weather forecasting indicating rainfall further east into the Kootenays. If these patterns shift west into the South Interior additional rises on river levels are possible and may be above peak levels experienced over the past couple of days. Current forecasting is indicating that flows should remain below the 2-5 year range throughout the region. If precipitation remains lighter through the region, as forecasted, rivers should stabilize and recede through the week.
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.
