Blizzard live updates: Snow totals top 2 feet as wind gusts reach 80 mph

Massachusetts Gov. Maura Healey said Monday afternoon she has instituted a travel ban for parts of the south coast and Cape Cod.

"We needed to do this because this is a particularly hard-hit area, we need to have the ability for all essential vehicle travel to be able to go through and anybody who doesn't need to be on the road should not be on the road," Healey said during a press briefing.

The travel ban is in effect for Plymouth, Bristol and Barnstable counties, the governor said.

More than 5,660 flights have been canceled in the U.S. as of Monday afternoon, according to FlightAware. Nearly 1,900 flights on Tuesday are also canceled.

Airports in the New York City region, Boston and Philadelphia are particularly impacted.

American Airlines said it expects to restart flights at the New York City-area airports and Boston late Tuesday morning, while flights have resumed in Philadelphia and D.C.'s Ronald Reagan Washington National Airport.

Rhode Island is seeing its largest snowfall on record, with 32.8 inches and counting in Providence as of Monday afternoon.

Long Island also saw its largest snowfall on record, with 29.1 inches in Islip as of Monday afternoon.

Elsewhere, snow totals have reached over 27 inches in Newark, New Jersey -- the second largest on record; 14 inches in Philadelphia, the city's biggest snowfall in 10 years; and 19.7 inches in New York City's Central Park, the ninth largest on record.

The storm is knocking out power across the Northeast, with Massachusetts and New Jersey hit the hardest with 280,000 and 120,000 customers without power respectively.
