The area's deepest snowfall on Sunday was 20 inches (50 cm), recorded in Ipswich, Massachusetts, a coastal town northeast of Boston, said NWS meteorologist Benjamin Sipprell.

Relentless winds were expected to pile up dangerous drifts of the lightweight snow, Sipprell said.

Across the state, about 600 members of the National Guard were helping out during the blizzard, said Massachusetts Governor Charlie Baker.

Conditions were so bad in New Hampshire that the town of Alton called off its annual ice carnival this weekend.

While still shivering from the brutal cold expected to last through Monday, the East Coast is bracing for another storm front forming near the Tennessee Valley.
