A powerful early season storm is moving across Atlantic Canada today, bringing heavy, wet snow and winds strong enough to cause coastal flooding in several provinces. Environment Canada has issued multiple snowfall warnings across Nova Scotia and Newfoundland, where conditions began to deteriorate overnight.

Forecasters say communities under yellow level alerts can expect 20 to 30 centimetres of snow by Wednesday afternoon. Higher risk areas in northern Cape Breton and parts of central Newfoundland remain under orange alerts, with totals that could reach 50 centimetres by evening. The agency warns that most of the system will fall as wet snow, though coastal areas may see periods of mixing with rain.

Wind gusts between 80 and 100 kilometres per hour are expected along exposed shorelines, creating dangerous surf and higher than normal water levels. Officials say the combination of strong winds and heavy snow could lead to power outages and travel delays across the region.

New Brunswick’s eastern coastline is also under a special weather statement, with forecasters predicting up to 15 centimetres of snow. National transportation routes, including flights through Halifax and St. John’s, may experience delays that could affect travellers connecting to Western Canada, including those flying to Vancouver, Calgary and Edmonton.
