Winter weather warnings issued once again for Atlantic Canada

Southern New Brunswick, which has already received more than one metre of snow in the past week or so, is expected to get another 10 to 15 centimetres Thursday.

Saint John remains under a local state of emergency declaration as the city continues to deal with the overwhelming amount of snow.

Northern New Brunswick has an extreme cold warning in effect, with temperatures expected to plunge to –35 C or below Thursday night and Friday morning. 

A trough of low pressure tracking across the region is bringing periods of rain to much of Nova Scotia. However, that is expected to change to heavy snow Thursday evening, with Environment Canada warning that the northern part of the province and Cape Breton can expect between 20 and 30 centimetres or more of snow.

The Halifax region is in for a mixed bag during the day, with 15 to 20 centimetres of snow expected by Friday morning, after rain tapers off in the evening.

The entire island of P.E.I. is also under a snowfall warning.

Environment Canada warns that periods of rain or flurries ahead of Thursday's low pressure trough will change to snow, at times heavy, late in the afternoon or evening. That snow will be accompanied by strong and gusty northerly winds giving occasionally reduced visibility in blowing snow overnight and Friday morning.
