The northeastern United States is bracing for another bout of potentially deadly weather, after a rare, mid-autumn blizzard killed at least eight people.
The pre-winter storm this week dumped more than 1.8 metres of snow in some areas, including the hard hit city of Buffalo in the western part of New York state.
Forecasters have predicted that the wintry deluge could set a record for the heaviest snowfall ever in the United States in a 24-hour time span.
The National Weather Service in its bulletin on Thursday, said an extra 60 to 90cm of "lake effect snow", created when frigid air moves over warm lake waters, could fall on Thursday.
New York Governor Andrew Cuomo, who travelled to Buffalo on Thursday for a firsthand look, said at a press conference that it may even be necessary to cancel an NFL football game on Sunday between the local Buffalo Bills and the New York Jets - sacrilege in a sport that many fans insist is most enjoyable when the weather is at its worst.

"Everybody would love to see a Bills game go forward, but I think even more, everybody wants to make sure public safety comes first," Cuomo said.
"At this point in time, doing what we have to do with the driving ban and everything we just said - staying off the roads - would make a Bills game impractical," he said.
The snow advisory will remain in effect through Friday, said the NWS, which warned of treacherous conditions, including near-zero visibility, and even the possibility of "thundersnow" - snow with thunder and lightning.
The snowfall is equivalent to around a year's supply of snow in just two days and could yet prompt a federal disaster declaration, local officials said.
