Coming rain could mean flooding, warns Conservation Authority

Sault Ste. Marie and area could experience localized flooding in low-lying areas should the coming weather system bring heavy rainfall and thunderstorms.

"The flood control channels managed by the SSMRCA are currently operating at normal levels. With the forecasted heavy rainfall, these channels are expected to have high water levels and flows," says a news release issued by the Sault Ste. Marie Region Conservation Authority (SSMRCA). "It is crucial to note that water in rivers, streams, and channels will be fast flowing during and after the rainfall event."

Full text of the SSMRCA release follows:

The Sault Ste. Marie Region Conservation Authority (SSMRCA) is issuing a flood outlook statement to residents regarding current watershed conditions. Flood forecasting and warning are part of the Conservation Authority’s provincially mandated responsibilities. This statement is sent out so that residents can be informed and aware.

A low-pressure system is expected to bring significant rainfall from tonight through Thursday night. The forecast predicts heavy rain with potential two-day accumulations ranging from 30 mm to 45 mm, and an additional 10-20 mm possible due to localized thunderstorms.

As of the latest observations, local rivers, creeks, and streams are at normal levels. However, the anticipated rainfall is likely to generate substantial runoff. This may increase the risk of overland flow and localized flooding in low-lying areas, and urbanized zones with poor drainage.

The flood control channels managed by the SSMRCA are currently operating at normal levels. With the forecasted heavy rainfall, these channels are expected to have high water levels and flows. It is crucial to note that water in rivers, streams, and channels will be fast flowing during and after the rainfall event.

The SSMRCA will continue to monitor stream flows throughout the watershed and provide updates as new information becomes available.

Residents and visitors are strongly advised to stay away from flood control channels and all waterways. Fast-moving water and slippery stream banks present significant hazards. Please ensure that children and pets are kept away from these areas.

This statement is in effect until Nov. 5, 2024.
