FINCH — Environment Canada is forecasting rainfall amounts ranging from 20 to 30 millimetres this week, while daytime temperatures are expected to remain above freezing for the next two weeks. The nice spring weather has caused a significant melt of the snowpack, and the result has been an above normal water level, though still within average ranges for this time of year.
However, SNC anticipates the coming warm temperatures to cause a further rise in water levels. Additionally, Ice cover in rivers and streams may break up due to warm temperatures and higher flows, increasing the risk of ice jams and associated overbank flooding. Higher than normal water levels may also cause nuisance flooding in low-lying areas.
Residents are advised to stay away from rivers as the weather may rapidly increase river flows, and banks might be unstable and slippery. Parents are encouraged to explain these dangers to their children. Residents in flood-prone or low-lying areas historically susceptible to flooding should also take the necessary precautions to protect their property, such as:
- Ensuring the sump pump is clear, in good working condition and has a backwater valve on it.
- Having a portable generator and backup pump available.
- Ensuring downspouts are clear and the outlet is at least 3 m from the dwelling.
- Removing or securing items that might float away as flows increase.
- Removing valuable items from basements or lower floors that could be subject to flooding.
- Keep emergency phone numbers handy.
- Familiarize yourself with your municipality’s emergency preparedness plan.
This flood advisory will stay in effect until April 7th.
