Environment Canada says snowfall will continue in parts of the Atlantic Canada Sunday night, resulting in 15 to 20 centimetres in some areas.

Heavy snow and ice pellets started falling Sunday afternoon, quickly turning roads in Nova Scotia into a slippery mess.

Halifax Regional Police advised residents to stay off the roadways if at all possible.

RCMP say there were 25 minor collisions on New Brunswick roadways Sunday due to weather conditions.

Environment Canada said up to 20 centimetres of snow had been expected in some areas of New Brunswick and Nova Scotia. Winds were light, so Environment Canada meteorologist Jean Marc Couturier says the snow fell quietly without blowing around.

Travel plans disrupted

Some flights at Halifax Stanfield International Airport have been delayed or cancelled. Air Canada and WestJet are advising anybody travelling to or from Maritime airports Sunday to expect flight delays and cancellations.

Couturier tells CTV News Channel that the snowfall has already weakened over western Nova Scotia, turning into rain in areas such as Yarmouth, N.S. The snowfall should ease off in the evening, he said, but there will be more coming to Cape Breton on Monday.

The temperature will also drop overnight leading to a much colder Monday for most of the Maritimes.

The Atlantic provinces have seen very little snow this year, so one place where Sunday’s snow will be welcome are the region’s ski hills. Several have remained closed this year, and those that are open have only a few beginner trails operating.

Staff at ski hills such as Crabbe Mountain in Bright Parish, N.B. say they need cold temperatures to settle in after Sunday’s storm hits.

“When we have cold and it’s also snowing, we can’t fire up our snow-making. But when we get low humidity and cold temperatures we can get the snow going,” says Crabbe Mountain’s Andrew Cuthberston.
