TORONTO — Airports hit by flight cancellations as a result of yesterday’s massive snowstorm are slowly working to get back on schedule.

Meanwhile storm conditions in Atlantic Canada have left tens of thousands of people without power.

Wind, rain and snow have been pummelling the region since yesterday afternoon when a powerful system dubbed by American forecasters as a ‘bomb cyclone’ moved in from the U.S. eastern seaboard.

Environment Canada meteorologist Darren Borgel says this “very large, very intense storm” will be memorable for its extreme winds, especially in Nova Scotia, which was also dealing with rain and storm surge.

Nova Scotia Power is reporting about 139,000 homes and businesses are without power.

NB Power is reporting outages for about 13,000 of its customers as New Brunswick gets hit with high winds and heavy snow in the north, and ice pellets and rain in the south.

Parts of Newfoundland and Labrador were expecting up to 30 centimetres of snow before changing to ice pellets and rain.

In the U.S., flights suspended at John F. Kennedy International Airport due to strong winds and whiteout conditions are resuming today. The Port Authority of New York and New Jersey said flights resumed at 7 a.m.

Air traffic suspensions at LaGuardia Airport have been lifted, but authorities advise passengers to contact their airlines regarding specific flights.

Flights in and out of Logan International Airport in Boston resumed Friday, and business is expected to pick up as the day progresses.

The flight-tracking site FlightAware reports nearly 5,000 cancelled flights across the U.S. Those flights include more than two-thirds of flights in and out of New York City and Boston airports.

The winter storm roared up the East Coast and dumped as much as 46 centimetres of snow from the Carolinas to Maine. It also has unleashed record flooding.

Forecasters say today will bring a blast of record-breaking cold air and bitter winds.
