North-east arctic blast sets record -108F wind chill on New Hampshire summit

Dangerously cold temperatures and wind chills dropped as low as -45 to -50F across the rest of the region

Arctic air in the US north-east on Saturday brought dangerously cold temperatures and wind chills including a record-setting -108F (-78C) on the summit of Mount Washington in New Hampshire.

Authorities in Massachusetts took the unusual step of keeping the South Station transit hub open overnight so homeless people had a place to sleep. Several cities set or tied record low temperatures. High winds brought down a tree branch on a car in western Massachusetts, killing an infant.
