The Maritime provinces are being blasted by a winter storm that has shutdown air traffic at Halifax International Airport and is also causing flight cancellations and delays at St. John’s International Airport.

A spokesperson for the Halifax Stanfield airport Peter Spurway says flights are at a standstill and the storm is expected to disrupt air traffic until sometime this afternoon.

Environment Canada says Nova Scotia will get the worst of the nor’easter, with more than 40 centimetres of snow expected in parts of the province by later today.

New Brunswick and Prince Edward Island will see around 15 to 30 centimetres of snow.

Wind warnings are in effect for northern Nova Scotia, with winds expected to gust to 90 km/h beginning this morning.

The low pressure system is expected to be south of Nova Scotia early today and will intensify as it tracks eastward up the province’s Atlantic coast towards Cape Breton.

It will then make its way to Newfoundland and Labrador, where a band of heavy snow is forecast to cross the central and western parts of the island later today.

Higher than normal water levels with rough pounding surf are expected along the Atlantic coast this morning.
