Storm to deliver snow and strong winds to Atlantic Canada on Monday

A strengthening winter storm is expected to affect much of Atlantic Canada on Monday, bringing heavy snow, strong winds and hazardous travel conditions to both Newfoundland and Nova Scotia.

Models show a rapidly deepening low-pressure system tracking northward along the eastern seaboard late Sunday before moving across or just east of Nova Scotia and toward Newfoundland on Monday.

In Nova Scotia, widespread snowfall is expected, particularly across northern and eastern areas, including Cape Breton, where 15 to 30 centimetres of snow is possible. Snow may fall heavily at times as the system intensifies. Southern and southwestern parts of the province, including the South Shore and Annapolis Valley, could see snow change to mixed precipitation or rain later Monday as milder air is drawn northward.

In Newfoundland, snow is expected to spread across western, central and northern parts of the island, with potential accumulations exceeding 20 centimetres in some areas. Eastern and southeastern regions, including parts of the Avalon and Burin peninsulas, may see snow transition to mixed precipitation or rain as the storm’s warmer air reaches the region.

Strong winds are forecast across both provinces, with gusts of 80 to 100 kilometres per hour possible, particularly along exposed coastal areas. The combination of heavy precipitation and strong winds is expected to lead to blowing snow, reduced visibility and difficult travel conditions.

The storm is expected to lift northward late Monday or early Tuesday, though lingering snow showers and gusty winds may persist in its wake.
