The Weather Network – A violent storm hits the East Coast with potentially damaging effects

Saturday, March 12, 2022, 8:06 a.m. – A powerful and potentially damaging storm will sweep across the East Coast this weekend, bringing heavy snowfall, intense winds and possible localized flooding from heavy rains to the region.

Batten the hatches, Atlantic Canada, it’s going to be a wild ride this weekend. A deepening low pressure system will cross the region with strong winds that can exceed 100 km/h in many places, potentially causing power outages and downed trees. It will also dump large amounts of snow and rain in parts of the region, with localized flooding and possible travel disruptions. The storm also has a good chance of setting a record for the deepest March low in Canada. More on what to expect this weekend and next week, below.

A potentially damaging and record-breaking storm begins its foray into the East Coast early in the weekend. Rain, snow, blizzard and wind warnings are dotted throughout the region.

Under pressure

If the center of the storm passed near one of these official observing stations in the region, it would break the record for the deepest low pressure system recorded in Canada during the month of March, according to Tyler Hamilton, meteorologist at The Weather network.

Precipitation associated with the storm will begin to infiltrate the Maritimes on Saturday morning.

In Nova Scotia, showers or periods of rain will start and then become heavy at times in the afternoon and evening before changing to scattered flurries or overnight or early Sunday morning. Localized flooding in low areas is possible.

In northern New Brunswick, it will manifest as snow. The snow will form and likely mix with rain or change to rain briefly in the afternoon before returning to snow at times heavy in the evening. The snow will then turn to showers early Sunday morning. Be prepared to adapt your driving to changing road conditions. Visibility can sometimes be suddenly reduced in heavy snow.


By the end of the storm, we could see 30-50mm of rain in parts of Nova Scotia and southern New Brunswick. Prince Edward Islanders can expect grand totals of 10-20mm through Sunday. Across the gulf to Newfoundland up to 50-100mm is possible for the southwest coast so localized flooding is a threat. 15-30mm is possible for the Avalon Peninsula.

A rain warning is in effect for parts of Nova Scotia, New Brunswick and Newfoundland ahead of the threat of heavy rain. “Localized flooding in low-lying areas is possible,” Environment and Climate Change Canada (ECCC) said in its warning for Halifax.

The biggest problem will be the powerful gusts of wind, which threaten to bring down trees and power lines, so power outages are likely. Expect wind gusts of 90-100+ km/h in many areas around Nova Scotia, Prince Edward Island, New Brunswick and Newfoundland, the gusts the strongest being probably near the coast.


The strongest winds are expected to blow over exposed areas, particularly the eastern regions of the province, where wind gusts could reach up to 110 km/h.

Very heavy snow is expected in northern New Brunswick, the Gaspé Peninsula, northern Newfoundland and much of Labrador.

15 to 30 cm of snow is possible for northern New Brunswick and northern New Newfoundland. We could see 40-60cm of snow across Labrador including Happy Valley-Goose Bay. Blizzard conditions are possible during periods of heavy snowfall and high winds.
