A snowstorm is expected to pound the Maritimes all day on Wednesday as the low pressure system tracks up the Bay of Fundy.

"Much of the area will experience blizzard­-like conditions with frequent white­outs," says CBC meteorologist Peter Coade, before the storm moves out into the Gulf of St. Lawrence tonight.

A winter storm warning is in place for today for nearly all of New Brunswick. Woodstock and Carleton County, Grand Falls and Victoria County and Edmundston and Madawaska County are the only areas of the province not under a warning or advisory.

"Hazardous winter conditions are expected," says the statement from Environment Canada.

"Snow at times heavy and blowing snow over southwestern portions of the province will spread northeastward this morning. Total snowfall amounts of 15 to 25 centimetres are currently expected."

Winds are forecast to continue throughout the day, gusting to 70 km/h and causing blowing snow and reduced visibility.

The snow is expected to taper to flurries by this afternoon.
