Current Watershed Conditions, Flood, and Drought Messages:

Weather Forecast: Environment Canada is forecasting a significant weather system that is expected to pass through the region beginning Thursday afternoon until Friday morning.

The current forecast estimates total precipitation amounts of up to 35 mm in some areas, with much of the rain occurring Thursday afternoon before tapering off early Friday morning. A risk of freezing rain is also a possibility. Temperatures are forecasted to be above freezing Thursday and Friday contributing to snow and ice melt.  

Environmental Conditions: Precipitation and snowmelt, combined with frozen ground conditions, will increase water levels and flows in rivers, potentially causing nuisance flooding in low-lying areas. Unstable ice conditions may also be present in systems.  

Risks: All rivers and streams across the jurisdiction will result in higher water levels, fast flowing water and slippery or unstable banks. Additionally, these conditions elevate the risk for ice breakup and ice jams at bridges, culverts and other areas producing localized flooding concerns in low lying areas.

ACTION: Residents are advised to exercise extreme caution when near rivers and
waterbodies due to high river flows and slippery conditions. Parents are encouraged to explain these dangers to their children.

Residents in flood prone or low-lying areas, historically susceptible to flooding, should take the necessary precautions to protect their property. Please ensure:

  • Sump pump is clear, in good working condition and has a backwater valve on it.
  • Easy access to portable backup generator and pump.
  • Downspouts are clear and the outlet is at least 3 m from the dwelling.
  • Securing items that might float away as flows increase.

Duration: This water safety statement is in effect until February 20, 2023 at 5 PM or until an update has been issued.

SNC monitors the water levels and weather forecasts as part of the Flood Forecasting and Warning Program. Updates are provided as conditions change.
