What is the November storm approaching Newfoundland?

The November storm approaching Newfoundland is a rapidly intensifying weather system that is expected to undergo bombogenesis, a rapid deepening process, leading to intense wind gusts, heavy rainfall, and possible snow.

Newfoundland Faces Powerful November Storm Fueled by Bombogenesis

Q: How will the Newfoundland weather bomb impact the region?

The Newfoundland weather bomb is expected to bring intense wind gusts of 90-100+ km/h, with gusts exceeding 110 km/h possible, especially around Sable Island and southeastern coastal Newfoundland. Heavy rainfall accumulations of 50-75 mm are expected in Cape Breton and along the Burgeo coast, with widespread amounts of 30-50 mm across the Avalon Peninsula. Wet snow may also develop in higher elevations in western Newfoundland and Labrador, potentially leading to power outages, downed trees, minor structural damage, localized flooding, and coastal erosion.

Q: What is the cause of the Newfoundland weather bomb?

The Newfoundland weather bomb is being fueled by a combination of factors, including a deep, cut-off trough interacting with the warm waters of the Gulf Stream, generating a sharp temperature contrast between the ocean and the air. This, combined with the phasing of two upper-level troughs, is creating the conditions for the storm to undergo rapid intensification or bombogenesis.

Newfoundland Faces Powerful November Storm Fueled by Bombogenesis

On November 3rd, 2025, a significant storm is developing and showing signs of rapid intensification. By Monday afternoon, a deep, cut-off trough is expected to interact with the warm waters of the Gulf Stream, generating a sharp temperature contrast between the ocean and the air.

Within 24 hours, a powerful low-pressure system is anticipated to approach Newfoundland. The storm will likely undergo bombogenesis, a rapid deepening process that turns the storm into a formidable low as it approaches Newfoundland on Tuesday.

Residents of Newfoundland and the surrounding region are bracing for the potential impacts of this powerful storm. Intense wind gusts of 90-100+ km/h are expected, with gusts exceeding 110 km/h possible, especially around Sable Island and southeastern coastal Newfoundland, including St. John's and the Avalon Peninsula. Heavy rainfall accumulations of 50-75 mm are expected in Cape Breton and along the Burgeo coast, with widespread amounts of 30-50 mm across the Avalon Peninsula. Wet snow may also develop in higher elevations in western Newfoundland and Labrador.
