Heavy rain warning issued for parts of southern Ontario

Environment Canada has issued a heavy rain warning for parts of southern Ontario, with rainfall amounts of 30 to 50 millimetres possible through Saturday and into the overnight hours.

The weather agency said a low-pressure system moving through the region is expected to bring periods of heavy rain north of Lake Erie and Lake Ontario.

Rain is forecast to gradually transition to drizzle from west to east, beginning Saturday evening in southwestern Ontario and continuing into Sunday morning for areas near eastern Lake Ontario.

Environment Canada warns that localized flooding in low-lying areas and water pooling on roads may be possible as rainfall accumulates.

Officials are also encouraging the public to consult their local conservation authority or the Ontario Ministry of Natural Resources for updated flood information.
