‘Weather bomb’ threatens the East Coast with snowfall warnings
It is predicted that there will be more than 20 cm of snowfall on Friday across much of Atlantic Canada.
Low-pressure systems intensify rapidly as they approach a region, which is likely to reach the ‘weather bomb’ criteria by falling 24 millibars in just 24 hours.
Snowfall amounts of 15-25 cm are expected across parts of the Maritime provinces, while several hours of freezing rain are expected across much of Newfoundland’s interior.
Considering the changing road conditions, drivers are encouraged to plan ahead.
It is likely that holiday travel plans are also in motion, therefore you should stay aware of the weather, and keep informed of all local warnings.
Windy conditions are likely to prevail throughout the region as well, resulting in the possibility of localized power outages. Ensure that your devices are charged prior to the arrival of the storm.
During Thursday, the first system swept across the Atlantic provinces as a prelude to the main course which arrived on Friday.

Throughout the day on Saturday, this second, stronger system will track south of the Maritime provinces overnight Friday before making its way into Newfoundland.
A southerly track of this system will affect parts of southern New Brunswick and much of Nova Scotia with heavy snowfall.
There have been occasions when peak snowfall rates have reached as high as 5 cm per hour.
Some southeastern parts of Nova Scotia may experience rain during the event, which may result in more slush.
Halifax may also see some ice pellets, but the risk of the icy mix will be greatest just east of the city.

Outages and Whiteouts Possible
Whiteout conditions could be possible in the Maritimes and western Newfoundland. Avalon may see gusts up to 90 km/h with winds between 50-70 km/h.
Windy conditions and wet snow may also cause power outages.
