Freezing temperatures are expected along the Atlantic coast until at least late Sunday night.

Thursday night in Nova Scotia, CBC meteorologist Kalin Mitchell said to expect lows of -14 to -20, as well as lows of -23 inland — that’s without factoring windchill.

Fire crews in Nova Scotia are gearing up for the busy days ahead as the temperature drops to what feels like -34 C and a blizzard warning settles on the province.

Lloyd Currie, division commander with Halifax Regional Fire, said burst pipes and carbon monoxide alarms have firefighters responding to several calls an hour.

He said they can expect more calls as the pipes in some of Halifax’s old buildings expand.

“They’re okay when they freeze, but as they start to thaw that’s usually when they break,” Currie said. "It's that cold that the pipes are just breaking from freezing."

Environment Canada has issued a blizzard warning for the Halifax region, the South Shore and Colchester, Cumberland and Guysborough counties. The rest of the province is on a storm watch.

CBC meterologist Peter Coade said a disturbance developing along the American seaboard on Thursday will intensify as it moves towards the Maritimes.

He said snow will start blowing in southwestern Nova Scotia on Thursday afternoon and spread across the province. According to the forecast, Thursday will feel like -27 C. Snow began falling in parts of Nova Scotia Thursday night.

On Friday people can expect between 15 and 30 centimetres of snow in most areas.

The weekend is shaping up to be sunny. 

"We're expecting that there will be a few more calls with pipes letting go," said Currie. "A lot of travel time, but we still have to go because you never know, it could actually be a fire when the alarm goes off." 

In preparation for the blizzard, the Halifax Regional Municipality is initiating a winter parking ban for early Friday morning.

Vehicles will not be allowed to park on streets between 1 a.m. and 6 a.m. so snow plows can get to work. 

Also, the Friday ferry crossings between Digby and Saint John, N.B. has been cancelled.

Police are also reminding motorists about the importance of driving according to weather conditions, that means:

  • Driving slower than posted speed limits.
  • Allow extra time for your commute.
  • Allow extra space between you and the car in front of you so you can stop in time.
  • When approaching a red light or stop sign, give yourself more time to stop.
  • Be mindful of pedestrians at intersections and crosswalks.
  • Be sure to clear your vehicle completely of snow and ice, especially windows and mirrors.
  • Be sure to turn on your vehicle's lights so your brake lights are visible.
