With heavy snowfall and winter storm warnings still in effect for Tuesday evening in many parts of Quebec and the Maritimes, snowplows are out in force, competing for space on snow-clogged roads with commuters who couldn't or wouldn't leave their cars at home.

The City of Montreal encouraged Montrealers to take public transit and said crews are working hard to clear the streets and sidewalks.

In Montreal, at least 1,000 pieces of snow-removal equipment were out on the streets early in the day to handle the 26-centimetre snowfall in the region. City spokesman Jacques-Alain Lavallée said workers are making bus stops, metro entrances, hospitals and schools a priority.

Lavallée refused to predict how long it would take to clear this latest dump of snow, in what has been one of the snowiest winters in 30 years — 269 centimetres and counting including the most recent dump, which is 17 per cent more than the annual average over the past three decades.

He said the snow removal operation will depend on the weather over the next few days.

"If the forecast calls for milder temperatures, we will have to assess whether all this is going to melt away, or whether we need to remove it as quickly as possible," Lavallée said.

On average, a 20-centimetre snowfall is cleared from the city's streets within four days.

More snow to come

Residents in the Montreal region and the southwestern Quebec had expected to see up to 15 centimetres of snow  — a record for this day, the last day of winter for 2013.

The storm is expected to hit the Maritimes overnight, bringing a mix of snow, rain and ice pellets as the temperature changes, creating a messy situation for the commute to work Wednesday morning.

Yarmouth is expected to be the first target. Then the system is expected to track across Nova Scotia, New Brunswick and Prince Edward Island, leaving behind 15 to 20 centimetres of snow in most areas.

The region is supposed to be hit again on Friday morning with another blast of snow heading into the weekend, said CBC meteorologist Peter Coade.
