The St. Clair Region Conservation Authority says Environment and Climate Change Canada has issued a rainfall warning for the region, with 20 to 40 mm of rainfall from Tuesday night to Wednesday. Locally higher amounts of rain are possible in areas that receive thunderstorms. Heavy downpours may cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.

Due to the recent snowmelt and rainfall, the watershed is seeing areas of ponding, standing water, and localized flooding in low-lying areas.  Watercourse levels have been falling since peak levels reached Sunday but remain high going into another significant rainfall event. The ground is saturated and will not have the ability to soak up more water. Water levels are expected to start rising again Wednesday and remain high into next week. Depending on the timing and amounts of rain received, water levels could rise rapidly.

Of note is that temperatures are expected to return to the freezing mark by late Wednesday night and will hover close to freezing through to Friday morning. This should help slow the generation of runoff contributing to watercourses.

Officials remind you to avoid watercourses and flooded areas due to dangerous conditions, slippery banks, unsafe ice cover and cold, swift-moving water. Children and pets should be kept away from the water.

There are several road closures already in St. Clair Township, Stanley Line between Kimball Road and Waubuno Road
