OTTAWA - Christmas across much of Canada was warmer than normal, with above zero-temperatures from Ontario to the Maritimes while the West Coast braced for heavy rains.
Environment Canada issued fog advisories Monday for much of Ontario, including a large swath spanning Niagara to Belleville in the province's east.
The advisory initially included Windsor in the southwest, but shifted eastward through the afternoon to start just outside London, and expand through to Muskoka and Lanark County.
"Generally not what people want to see around Christmas if they want to see a white Christmas," said Environment Canada meteorologist Ryan Rozinskis.
The weather agency predicted near-zero visibility on Christmas morning, with fog remaining into the afternoon for some areas, followed by dense fog developing again in the evening.
"But that should be the last of the really foggy nights, at least for now, because we're going to be getting into some rain tomorrow," Rozinskis said. "It's a very light rain or drizzle spreading all over southern Ontario and that's going to help reduce the amount of fog."
The agency warned travel could be hazardous due to reduced visibility and said that drivers should slow down, watch for tail lights ahead and be prepared to stop.
Fog is not unusual for this time of year, especially when there are mild conditions.
"The ground can be colder, the lakes are starting to cool down and then we have this surge of warmer, moister air," said Rozinskis.
"We also have less daylight so less potential of heating, which will also prevent fog. So basically it's a good pattern when you get warm moist air over southern Ontario in winter to start seeing fog."
In the nation's capital, children awoke to a cloudy sky and small clumps of dirt-covered ice on the ground. Ottawa reached 2 C Monday afternoon and was forecasted to reach freezing temperatures overnight.
A week ago, Environment Canada said Ottawa had the warmest Dec. 18 since record-keeping started in the city some 134 years ago, reaching 7.1 C on that date.
The mild start to the season has locals concerned about the Rideau Canal, which bills itself as the world’s largest outdoor ice rink. Last year, the skateway didn’t open for the first time in 53 years.
Paul Allen wore a light coat that he zipped halfway closed during a midday stroll alongside the canal with his wife Hilary.
"It's mixed emotions, right? It's beautiful for walking," said Paul, an Ottawa native who recalls shovelling six-foot-high snowbanks on Christmas mornings as a child.
The couple is anxious but optimistic the canal will open for skating. They noticed open water last week, but pointed out the thin layer of ice Monday.
Hilary is hoping this will be a better year for cross-country skiing. "For sure, climate change is having an impact; I don't think you can dispute that," she said.
The ºÃÉ«tv Capital Commission, the Crown corporation that oversees the skateway, said the Canal can only open if there are at least 10 consecutive days of temperatures between -10 C and -20 C, which typically occurs in mid-January.
Vadim Spac said Monday the muddy ground isn't very festive for his wife and two kids, but he noticed that their brown poodle was beaming in the mild weather.
"We need to be happy with what we have," he said with a smile.
It was a different story closer to the North Pole, however, with Iqaluit, Nunavut, posting a blizzard update on social media that warned road conditions were snowy.
"We are receiving reports of residents getting stuck. Please stay off the roads unless absolutely necessary," the city's warning on Facebook stated.
In late November, The Weather Network had forecasted a mild Christmas season for Ontario and Quebec, but said much colder temperatures should follow.
Up in northern Ontario, Environment Canada says "a prolonged period of freezing rain" is forecast for areas such as Timmins and Thunder Bay starting Monday night. It is expected to continue for most of the day on Tuesday, with upwards of 10 millimetres of ice building up on some surfaces.
In Montreal, only small traces of an early December snowstorm remained on the ground as the sun shined on Christmas morning. Temperatures peaked midday at 5 C.
The agency's historical weather data shows Montreal's average daily maximum December temperature was -1.4 C between 1981 and 2010.
Fredericton also reached 5 C on Christmas Day; the average temperature for this time of the year is a high of -2.6 C and a low of -13.5 C. The low Christmas night is forecast to be 1 C.
Charlottetown reached a seemingly balmy 6 C. The average high for this city is -1.5 C and the average low is -10 C at this time of the year.
Prairie cities are experiencing an unusually brown Christmas this year, with many getting just a few centimetres of snow in December.
In Edmonton, less than four centimetres has fallen this month, most of which has already melted, and no snow was recorded at all in the city in November.
Temperatures were below freezing across much of the West on Christmas Day, but not a flake is forecast for the next week from the Rocky Mountains to Winnipeg.
In B.C., Environment Canada issued several wind and rainfall warningsall along the coast from the Alaska to Washington borders, particularly on Vancouver Island.
The agency warns of a "strong weather system" approaching the B.C. coast, forecasting strong winds and heavy rainfall to hit by midday and into Boxing Day.
Warnings issued early Christmas morning say island communities including Tofino, Uclulet and elsewhere could see up to 120 mm of rain, potentially causing "localized flash floods" after heavy downpours.
Environment Canada has also warned of strong winds hitting coastal communities with gusts of up to 120 kilometres an hour, with another storm on approach potentially bringing strong winds into Tuesday and Wednesday.
