A dense fog advisory and freezing rain warning in the Ottawa region has been lifted, Environment Canada says.
Early Friday afternoon the national forecaster said dense fog could appear cross the Ottawa Valley and create near zero visibility.
The appearance of the fog could be sudden, making driving dangerous, Environment Canada said.
The light, freezing drizzle that started Friday morning continued early into Friday afternoon, though a freezing rain warning across the Ottawa Valley has since ended.
Highways, roads, sidewalks and parking lots may still be very slippery.
The regions affected by the freezing rain and drizzle include Ottawa and nearby areas like Smiths Falls, Cornwall and Prescott, as well as areas throughout southern Quebec, including Pontiac, Wakefield and Gatineau.
The high on Friday in Ottawa is expected to reach 5C and the low on Friday night is expected to dip down to –2C.
Storm heads to Ottawa on Sunday
Environment Canada has also issued a special weather statement in the region for Sunday. Forecasters say a winter storm may bring either heavy snow or freezing rain to eastern and central Ontario as well as western Quebec.
Travel conditions are expected to "rapidly deteriorate" Sunday afternoon and power outages are possible, said Environment Canada.
Kingston is not affected by the freezing rain warning nor the special weather statement.
The city will see a few showers on Sunday morning but the rain will end by afternoon. Environment Canada forecasts a high of 9C in Kingston and a low of –1C on Friday.
