A flood watch has been issued by the Lower Thames Valley Conservation Authority.
Strong winds from the East and North East are expected to continue Sunday with gusts to 60 km.
There is also a chance of up to 15 mm of rain.
This could raise waters in the western basin of Lake Erie and Rondeau Bay.
The waves on the lake are expected to reach 1-2 m.
This could also mean more shore erosion.
