The Lakehead Region Conservation Authority has issued a Flood Watch for Thunder Bay and the Lakehead Region.

The conservation authority advises that 20 to 40 millimetres of rain is expected over the next 24 hours. There is also a risk of thunderstorms that could produce an additional 25 to 50 millimeters of rain.

Waterways are expected to see rising water levels and the conservation authority is asking residents to keep an eye on the forecast and to exercise caution around waterways.

High flows and unstable slippery banks could be dangerous, and flooded roadways should be avoided.

A Flood Watch is issued when the assessed conditions indicate that there is a chance that flooding will develop. Conservation authority staff plan to monitor conditions as part of its flood forecasting and warning program.

The flood watch is expected to remain in effect until noon on Wednesday, May 22, 2024.
