About two to five millimetres of freezing rain is expected to accumulate on surfaces in the Ottawa area overnight, according to a warning posted on Environment Canada's website.

The freezing rain is expected to begin late in the evening and last about two to six hours.

The forecast for Friday night calls for cloudy skies with a 60-per-cent chance of flurries or freezing drizzle in the evening and after midnight before turning to freezing rain overnight.

Fog patches are also expected to develop overnight, with the low hitting 6 C. The temperature is then expected to rise to 2 C by morning.

On Saturday, Environment Canada expects the freezing rain to change to rain in the morning. About 15 to 25 mm is forecast to fall. Fog patches will dissipate late in the evening and the high should reach 7 C.

City crews were preparing Thursday for the melt, which could lead to a lot of pooling.

The Rideau Canal Skateway will close as of midnight Friday due to the weather, the National Capital Commission announced.

"Snow, freezing rain or water on the ice surface may hide serious deterioration of the ice thickness. For this reason, the NCC urges the public to refrain from venturing onto the Rideau Canal Skateway," the NCC posted on its website.
