Widespread windchill warnings cover much of Atlantic Canada with windchill values expected to dip as low as -40 in some places Wednesday.
The frigid temperatures follow a day of snow, strong winds and poor driving conditions in Nova Scotia and Newfoundland.
The storm cancelled classes across much of Nova Scotia Tuesday and in Newfoundland, students were dismissed after the morning session.
"Between 5-10 cm of snow was recorded in southern Nova Scotia, while places like St. John's Newfoundland saw over 20 cm Tuesday," says Mark Robinson, a meteorologist at The Weather Network.
The heavy snow led to some road closures across eastern Newfoundland Tuesday night and emergency personnel say they responded to many accidents through the evening hours.
RCMP reported that all roadways on the Avalon Peninsula and as far west as Clarenville were extremely slippery with snow and ice.
Drivers could face another challenging commute on Wednesday with strong, cold winds expected to cause snow squalls along the south and west coasts through the day.
Environment Canada warns of reduced visibilities with significant blasts of heavy snow at times.
Some schools in the eastern and western regions of Newfoundland are closed for the morning.
"And in addition to the snow, much of Atlantic Canada will face frigid temperatures for the next couple of days," says Robinson. "Cold arctic air combined with northwesterly winds will result in cold temperatures and extreme windchill values."
