Flood watch issued for Greater Sudbury watersheds as rain and snowmelt raise flooding risk

Greater Sudbury residents are being warned to watch for rapidly changing water conditions as a flood watch takes effect Friday afternoon and remains in place until April 16. The advisory comes as recent snowmelt, frozen ground and a forecast of 30 to 50 millimetres of rain combine to increase the risk of rising water levels and localized flooding.

Rain, frozen ground and runoff could push water levels higher

Officials say water levels may rise quickly over the next several days, particularly in smaller watercourses and urban drainage systems where runoff can collect fast. Pooling water and localized flooding are possible in low-lying areas.

Frozen ground can make conditions worse during spring melt because rainfall is less able to soak into the soil, sending more water directly into creeks, ditches and stormwater systems.

Public urged to stay back from fast-moving water

Residents are being reminded to use caution near rivers, streams and drainage channels. Cold, fast-moving water can be extremely dangerous, while riverbanks and shorelines may be slippery and unstable.

Parents and pet owners are being urged to keep children and animals well back from the water.

Some major river branches not included in advisory

The flood watch does not include the main branches of the Whitson, Vermilion, Onaping or Wanapitei rivers.

Officials say conditions will continue to be monitored, with further updates expected if the weather changes or water levels rise more quickly than forecast. Residents are being asked to stay alert through the weekend and into next week.
