Environment Canada has issued a special weather statement for the region calling for significant amounts of rainfall over the weekend.
Localized rain amounts are expected to reach between 50 to 100 millimetres over the next couple of days in Bruce Peninsula, Sauble Beach, Tobermory, Hanover, Dundalk, Southern Grey County, Owen Sound, Blue Mountains, Northern Grey County, Saugeen Shores, Kincardine, Southern Bruce County, Goderich, Bluewater, Southern Huron County, Stratford, Mitchell, and Southern Perth County.
Environment Canada says the excess of moisture in the atmosphere will allow rain to fall heavy at times.
Residents are advised heavy downpours can cause flash flooding and water pools on roads.
For more information on flooding, residents can visit their local conservation authority or Ontario Ministry of Natural Resources and Forestry District website.
