Emergency crews in New York were scrambling to rescue marooned residents from what authorities called the “blizzard of the century,” a relentless storm that has left 27 dead in the state and taken at least 60 lives nationwide, according to an NBC News tally.

In New York state, authorities have described ferocious conditions, particularly in Buffalo, with hours-long whiteouts, bodies being discovered in vehicles and under snow banks, and emergency personnel going “car to car” searching for more motorists, alive or dead.

On Monday night, US president Joe Biden issued a federal emergency declaration for the state of New York, authorising government assistance to bolster state and local recovery efforts.
