The Maitland Valley Conservation Authority has issued a flood warning for the Nine Mile River watershed.
That includes Lucknow and surrounding areas in the Township of Huron-Kinloss as well as the Nine Mile River area through the Township of Ashfield-Colborne-Wawanosh and the community of Port Albert.
They say flooding is imminent or already occurring in those areas.
The conservation authority says an intense band of heavy thunderstorms moved through the region early this morning, bringing 40 to 60mm of rainfall in a corridor from Goderich to Lucknow. Headwater areas of Lucknow are currently at flood stage. Riverine areas downstream of Lucknow throughout the Township of Ashfield-Colborne-Wawanosh and the community of Port Albert may experience flooding greater than what was observed during the 2008 and 2018 events.
Smaller streams and drainage systems along the Lake Huron shoreline are also at risk. Flooding and washouts of smaller channels and municipal drains may occur, and some shoreline gullies may experience severe erosion or localized slope failure.
Residents in low-lying areas near the Nine Mile River should monitor conditions closely and be prepared for possible flooding. Rural roads are at high risk of washouts, and fast-moving water and flooded roadways may create hazardous conditions. Residents are reminded to never drive through flood waters.
