With as much a 90 mm of rain possible over the next few days, officials are keeping a close eye on area waterways.
A flood watch has been issued by the St Clair Region Conservation Authority.
Heavy rainfall is expected to begin after midnight on Saturday, which could cause flooding in low-lying areas.
Winds from south and southwesterly directions have the potential to create a backwater effect, further elevating water levels in Wallaceburg.
