Environment Canada is warning residents in Windsor and Essex County that they are in for a wet day on Wednesday.
It issued a yellow warning for rain as a series of low pressure systems moves through the region. The region could see between 20 and 40 mm of rain.
The ground is already saturated, so there could be flooding in low-lying areas and on roads.
The Essex Region Conservation Authority issued a watershed condition statement earlier in the week, which will remain in effect until noon on Thursday.
