A yellow weather warning for rainfall has been issued for Waterloo region, Guelph and Wellington County with up to 40 mm rain possible Tuesday evening and overnight into Wednesday.
There is also a risk of thunderstorms.
Periods of significant rainfall are expected due to a series of low-pressured systems moving across southern Ontario.
Environment Canada warns that because the frozen ground has yet to thaw, rain is likely to pool on roads and areas of lower elevation.
People should avoid driving on flooded roads and to be wary of soft, slippery ground near rivers, creeks, and culverts, the warning says.
Flood warnings were issued across the region earlier on Tuesday morning, with flooding attributed to increased rainfall and melting snow piles.
Areas at risk of flooding include Drayton, Grand Valley, Conestogo, St. Jacobs, West Montrose, New Hamburg, Ayr, Cambridge, Six Nations, Brant County and the City of Brantford.
The temperature reached 18 C in Waterloo region on Tuesday. It was expected to drop to 3 C overnight, then rise to 5 C on Wednesday.
The forecast for Thursday says people should expect a chance of flurries and a high of 1 C.
