Parts of the Maritimes could be hit with more than 30 centimetres of snow Wednesday as a forecasted storm makes its way north from the U.S. eastern seaboard.
An Environment Canada map shows in grey where a special weather statement has been issued for a winter storm system of snow, freezing rain and rain Wednesday. The yellow area on the island is where a winter storm watch has been issued, with higher snowfall accumulations and the red areas are where wind warnings have been issued.
Environment Canada has issued a blizzard warning for Nova Scotia and Prince Edward Island.
In Newfoundland and Labrador, Environment Canada says, in advance of the system, snow is forecast to cross the island during the day on Wednesday, changing through ice pellets and freezing rain to rain for areas east of its track as temperatures rise.
A second low pressure system is expected to cross Newfoundland overnight Wednesday into Thursday, but the exact track of the low is uncertain at this time. A shift in the track will result in a similar shift to the rain-snow line which is currently forecast to split central Newfoundland. Any shift in the track will also result in a shift to the areas of highest snowfall and rainfall accumulations.
Snowfall accumulations in the latest forecast for the eastern half of the island are expected to be between 5 and 10 centimetres, with higher amounts of near 15 cm in central and western Newfoundland.
Environment Canada says some locations have the potential of receiving three to six hours of freezing rain before it changes over to rain or drizzle. Maximum rainfall amounts are expected to be along the south coast and will range from 25 to 40 millimetres by Thursday morning.
Strong southwesterly winds will develop over much of Newfoundland today as the low pressure system intensifies over Northern Labrador. Environment Canada says winds are expected to be strongest over the Northern Peninsula where gusts are forecast to reach 100 km/h this evening before easing overnight as the low moves further away.
In the Maritimes. snow is expected to track across Nova Scotia beginning later today with wind gusts of up to 50 km/h after midnight.
Wind gusts are expected to increase through the day on Wednesday with snowfall amounts of 20 to 30 centimetres in Nova Scotia and P.E.I.
The Maritime provinces were hit with a blizzard nearly three weeks ago.
The storm forced flight cancellations, interrupted public transit and closed roads, government offices, universities and businesses.
