Two weather systems will affect our area over the next two days. The first will move through today bringing some snow. The snow will then change to rain this afternoon or evening and may become heavy overnight as a second and much stronger system begins to move in. Both systems have the potential to deliver periods of heavy rainfall which will quickly turn into surface runoff. With the soils already saturated, we expect smaller drainage features to respond quickly and may experience localized or urban flooding. The larger watersheds will respond and may reach levels close to average spring runoff conditions. No major flooding is expected at this time, but watercourses may reach or exceed their banks. Seasonal flooding of low-lying and poorly drained areas is expected.
The remaining snowpack is restricted to woodlots, heavily drifted areas, and snowbanks. It will continue to reduce and may contribute to some of the runoff. Our river systems are clear of ice cover and should not be at risk to ice jamming.
Grey Sauble Conservation Authority would like to remind everyone that during spring runoff events, potential conditions exist that could pose a risk to personal safety. High flows, unsafe banks, melting ice or other factors could be dangerous for residents and pets. Stay back from riverbanks and away from fast moving water.
Grey Sauble staff will continue to monitor the weather and the flows and provide additional updates as needed. Watershed residents can access snow, stream flow and rain gauge data through our Watershed Conditions page on our website: https://www.greysauble.on.ca/water-management/current-watershed-conditions/.
This Statement expires April 3rd, 2023 at 12pm unless replaced by further updates.
