HALIFAX -- Parts of the Maritimes are digging out for the second time in three days as a winter storm sweeps through parts of the region.

Environment Canada meteorologist Barrie MacKinnon says a weather system near Cape Cod is responsible for the storm which was expected to bring up to 25 centimetres of snow to much of mainland Nova Scotia and southeastern New Brunswick by the end of the day Tuesday.

MacKinnon says up to 15 centimetres of snow was expected for northern New Brunswick, while lighter amounts of up to 10 centimetres were forecast for Prince Edward Island and Cape Breton.

The snowfall led to several flight delays at Halifax Stanfield International Airport and to event cancellations in some parts of the region.

RCMP in Nova Scotia say the conditions also caused more than a dozen traffic accidents across the province.

The most serious was a head-on collision around 2 p.m. on Highway 104 near French River, N.S., that sent a man and a woman to hospital with serious but non-life threatening injuries.

The latest snowfall follows a storm on Sunday that dumped up to 18 centimetres across areas of the Maritime provinces.
