Deadly snowstorm hits northern US

Snow covers a street at daybreak in BuffaloA massive snowstorm has wreaked havoc in the north-eastern US and left seven people dead, five in upstate New York.

After sweeping across the Great Lakes, the storm dumped 5ft (1.5m) of snow in the Buffalo area, with more forecast, bbc.com reports.

The storm caused five deaths in that area - one in a car crash, one trapped in a car and three from heart attacks.

Freezing temperatures were recorded across all 50 US states, including Florida and Hawaii, and there were more deaths elsewhere in the country.

"We have tried to get out of our house, and we are lucky to be able to shovel so we can open the door," said Linda Oakley, a resident of Buffalo.

"We're just thinking that in case of an emergency we can at least get out the door," she added. "We can't go any further."

Snowfall in Buffalo could break records, forecasters predictResidents were reported trapped in their homes and cars, and strong winds and icy roads caused motorway accidents and forced school closures in parts of the US.

More than 100 vehicles were reported trapped along a New York state roadway on Wednesday.

New York Governor Andrew Cuomo deployed more than 100 National Guard members to assist in clearing roads and removing abandoned vehicles.

"This is an historic event," he said. "When all is said and done, this snowstorm will break all sorts of records, and that's saying something in Buffalo."

The National Weather Service said some places could top the record for a single-day of snowfall, which is 6ft 4ins (1.93m).
