Flood Warnings and Advisories

Central Region - High Streamflow Advisory (MAINTAINED) – North Thompson Tributaries, North Okanagan, Nicola River (NEW), Salmon River (Salmon Arm)
ISSUED: 1:30 PM May 14, 2020

The River Forecast Centre is maintaining a High Streamflow Advisory for:

  • Tributaries of the North Thompson River around Clearwater and Barriere
  • Nicola River (NEW) 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

Rivers have remained high through the region due snowmelt rates and some rainfall events over the past week. Snowmelt from mid-elevations is beginning to ease as areas become snow-free and it is expected that the peak runoff from snowmelt in all but the high-elevation watersheds in the region is currently underway or has passed.


River levels have remained stable over the past 2-3 days with drier conditions and easing temperatures and snowpack. Flows are expected to remain high but stable over the next few days. Later this weekend and into early next week a pattern of unsettled weather is expected, with the potential for heavier amounts of precipitation. This may lead to another period of increased streamflow Sunday through Tuesday. At this time hydrologic modelling is indicating that flows may rise above levels that have been previously experienced this year.


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.

Levels of Warnings/Advisories:

  1. High Streamflow Advisory: River levels are rising or expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas is possible. This is the lowest level.
  2. Flood Watch: River levels are rising and will approach or may exceed bankfull. Flooding of areas adjacent to affected rivers may occur. This is the intermediate level.
  3. Flood Warning: River levels have exceeded bankfull or will exceed bankfull imminently, and that flooding of areas adjacent to the rivers affected will result. This is the highest level.
