HALIFAX — The last week of winter is starting with a bang in the Maritimes, as blizzard and winter storm warnings remain in effect through much of the region.

Environment Canada says parts of P.E.I. and New Brunswick can expect another 20 centimetres of snow Sunday on top of what fell overnight.

Airports across the Maritimes were showing mostly cancelled flights Sunday morning.

In Halifax, heavy snow followed by ice pellets led to poor driving conditions, with police reporting vehicles stuck in city streets and advising drivers to stay off the roads if possible.

Recreational facilities and post-secondary campuses across the city were closed Sunday morning because of the weather.

The low pressure system is expected to move on to Newfoundland late Sunday, bringing blizzard conditions to the island overnight and into Monday.
