Stay off stormy roads, police warn Maritimers

Stay home and off the roads, police are warning people in the Maritimes as a winter storm bears down on the region.

Thick snow is already falling in southwestern New Brunswick and parts of Nova Scotia. Between 15 and 30 centimetres of snow is expected for Nova Scotia as the system moves off the East Coast of the U.S. Sunday morning and past Cape Breton later in the evening.

Similar snowfall amounts are expected for southern New Brunswick, while the province's Grand Manan area could get up to 40 centimetres.

About 15 to 25 centimetres of snow is expected for P.E.I.

CBC’s meteorologist Peter Coade said the storm is moving faster and tracking further north than earlier predicted. That means more of the Maritimes will see rain that's expected to follow the snow later Sunday afternoon.

Flights cancelled 

Hardly any flights are flying in or out of the region’s airports. At the Halifax airport more than 30 flights are cancelled for Sunday morning and afternoon. Holiday travellers are being urged to call ahead to check on their flight's status.

The major airlines have been readjusting schedules well in advance of the storm.

Flights in and out of Moncton, Fredericton, Saint John, Charlottetown and Sydney are also severely impacted Sunday.

People travelling by boat are not much better off. The ferries that usually make the crossings between P.E.I. and Nova Scotia, Cape Breton and Newfoundland and Digby and Saint John are all tied up Sunday.

Code said tides will be high in the Northumberland Strait and storm surge could become a factor.

About 2,000 people lost power in the Halifax area just after 10 a.m. Nova Scotia Power hasn't said what caused the outage or when it will be back.
