Deadly Arctic winds tighten grip on US

THE Eastern Unites States were hit with another day of bitter cold and blustery winds that made it feel as cold as 40 degrees below zero in some areas, making icing roads, airplanes and outdoor exposure deadly.

With the demand for heat so high, officials in New England warned of possible rolling blackouts.

At least six people have died in the latest cold snap, including a hiker found in the White Mountains of New Hampshire.
