Environment Canada has issued both freezing rain and rainfall warnings for the city.

The national weather agency said in statements Thursday night that travellers in eastern Ontario "are urged to exercise caution as untreated roads may become icy and slippery."

After hours of overnight freezing rain, CBC Climatologist Ian Black said the city can expect as much as 20 to 30 mm of rain Friday.

Some areas could see as much as 40 millimetres of rain over the two days in eastern Ontario.

There is concern about water accumulation from melting snow, caused by a high around 7 C on Friday. The City of Ottawa says it’s planning for large puddles along many roads and asks residents to call 311 if they see a dangerously large puddle.

Winds are also expected to increase as the rain comes to an end Friday with gusts up to 70 or 80 kilometres per hour.

The Rideau Canal Skateway will be closed as of midnight Thursday in anticipation of the changing weather, the National Capital Commission announced Thursday.
