Environment Canada has issued a special weather statement for Waterloo Region, as icy conditions are expected for Friday.
The weather agency says heavy rain will continue overnight Thursday and there may be a brief period of freezing rain.
As temperatures drop, the rain will switch to snow sometime Friday – but that should taper off heading into the weekend.
In the meantime, roadways are expected to be icy and slippery – which means drivers will need to use extra caution.
The special weather statement is also in effect for Guelph, Erin, Arthur, Mount Forest, and Northern Wellington County and Southern Wellington County.
Due to the conditions, the Grand River Conservation Authority has issued a flood watch – as rising water levels are already affecting some bridges and roadways.
