Bitter cold temperatures and freezing wind chills continued throughout North America on Friday.
The winter storm that paralysed much of the northeast gave only a glancing swipe to Washington DC, where less than two inches (five centimetres) fell overnight.
The cold weather did not dampen the spirits of European tourists visiting the capital.
"The weather's like in Switzerland, but the wind is very cold here," said Swiss tourist Peter Schwander.
By Friday morning, the storm had moved on up into New England and left Washington to dig out.
Between two and eight inches (five and 20 centimetres) of snow was scattered across the Philadelphia on Friday morning.
Most school districts in eastern Pennsylvania were closed.
At a suburban Philadelphia road salt storage facility one man died when a 100-foot-tall (30.5 metres) pile of salt fell and crushed him on a backhoe.
As the snowfall has finished, many are bracing for a weekend of sub-zero temperatures.
Record wind chills, causing frostbite within just a few minutes, are expected across the country.
An Indiana resident worked on a creative approach to clearing his driveway by inventing a remote-controlled snow blower.
Former engineering student, Aaron Makin, originally created a remote-controlled lawnmower but converted it to a snow blower by adding chains to the tires to help with traction.
"I just like to try to figure out easier ways to do things, and be creative about it, and have some fun with it," Makin said.
Canada's Maritime provinces were dealt a wintry wallop on Friday as a blizzard bore down on the region all day, forcing the cancellation of flights, interrupting public transit and closing roads, businesses and state buildings.
Whiteouts prompted police to urge the public to stay off the roads as plough operators undertook the task of clearing snow, only to have wind-whipped drifts quickly build back up.
The snow could change to freezing rain by the time it reaches Eastern Ontario early on Monday.
