The Essex Region Conservation Authority has issued a flood watch for Windsor and Essex County.

Between 25 mm and 40 mm of rain is predicted to fall over the next 24 hours.

"A possibility of flooding exists along watercourses and in low lying areas for the entire Essex region," ERCA said in a release. "In addition, due to the potential for isolated downpours and due to the fact that wet ground conditions exist, there is an enhanced possibility of flooding and drainage problems throughout the entire region."
