Sydenham River, August 19, 2019.

The St. Clair Region Conservation Authority has updated Thursdays flood watch.

Water levels on the Sydenham River are rising thanks to last nights downpour, and some locations are expected to see some minor flooding into the natural flood plane areas, farmland and parks.

A gale wind warning is in effect for Southern Lake Huron with waves expected to reach 3-4 meters.

The conservation authority will continue to monitor conditions and issue flood information as necessary. 

This watch is in effect until Sunday.
