Nor'easter to impact Atlantic Canada later this weekend
Saturday, March 29, 2014, 6:19 AM -
A powerful and intense Nor'easter stormed through Atlantic Canada Wednesday -- and it was one for the record books.
That storm has now left the region -- just in time for two more systems to move in.
The first brought mostly rain to parts of Nova Scotia, with mixing and light flurries elsewhere.

The larger storm will move in Sunday and, while it won't be as record-breaking as Wednesday's Nor'easter, it will still pack a punch. On Saturday morning, snowfall and freezing rain warnings were already in effect in New Brunswick, along with rainfall and freezing rain warnings in Nova Scotia. Newfoundland and Prince Edward Island were both covered by special weather statements.
"New Brunswick will experience a longer period of snow with western portions of the province remaining snowy throughout the duration of the storm," says Weather Network meteorologist Doug Gillham.
"Central and eastern New Brunswick will experience prolonged freezing rain with a period of straight rain along the Bay of Fundy."
Up to 20 cm of snow is possible in southern portions of the province with up to 35 cm in northern communities.
More than 20 mm of freezing rain could fall in southern and central areas.
"Conditions are expected to quickly change from snow, to freezing rain and then rain," says Weather Network meteorologist Dayna Vettese.
"Up to 60 mm of rain is possible, along with 5-10 cm of snow before the system changes over."
Residents are being warned to prepare for wind gusts up to 70 kilometres per hour. In Cape Breton, gusts up to 100 km/h are forecast.

PEI will also start as snow before the system changes into freezing rain, followed by ice pellets.
"We're looking at between 5 and 15 cm of snow with 10 to 20+ mm of freezing rain and ice pellets," Vettese says, adding that wind gusts between 80 and 100 km/h are expected in the region.
Up to 25 cm of snow, accompanied by wind gusts around 100 km/h, will move in Sunday night.
"There's a threat for significant ice pellets and freezing rain across the Burin and southern Avalon," Gillham says.
Freezing rain brings with it the potential for messy roadways, downed power lines and snapped tree branches. Officials are warnings residents to prepare for the conditions.
WHAT'S THE FLOOD POTENTIAL?
This weekend's rainfall forecast, coupled with the significant snowfall that's already on the ground, has elevated the concern for ponding on roads and basement flooding.
Here's meteorologist Jaclyn Whittal with a more in-depth look at this weekend's flood potential:
