A giant winter storm is unleashing a second wave of heavy snowfall on the US north-east, as hundreds of thousands of people remain without power in the states in its southern wake.
About 550,000 homes and businesses are still in the dark and almost 1000 flights are cancelled on Friday.
The storm has been blamed for at least 22 deaths, including that of a pregnant woman struck by a snowplough, the BBC reports.
It is the latest miserable weather to pummel the winter-weary eastern US.
By early in February, Washington DC, Detroit, Boston, Chicago, New York and St Louis had recorded two to three times as much snow as normal by this time in the winter season.
This storm system has already dumped as much as 38cm of snow in the Washington DC region and 20cm around New York City by Thursday.
