Arctic air, coastal flooding, and high winds forecast for parts of Atlantic Canada

Dec 3, 2025 | 11:46 PM

Icy cold weather is sweeping into parts of Atlantic Canada starting today, while other regions begin to shake off the effects of yesterday’s nor’easter.

Environment Canada has issued a yellow warning for cold in New Brunswick, with temperatures forecast to drop to between -30 and -33 degrees Celsius, into Friday morning.

Meanwhile, most snowfall warnings have been lifted in Nova Scotia, except for a snow squall warning in the Cape Breton Highlands.

Along the province’s southwestern shores, from Digby to Yarmouth, the agency has posted a coastal flooding statement warning of elevated sea levels that may exceed high astronomical tides.
