Yes, you read that correctly. A hurricane producing feet of snow. It’s been a crazy year for tropical systems already, so why not?
Hurricane Larry is forecast to slide up the east coast of Greenland this weekend. When it gets there, it will have sustained winds around 60 to 70 mph, with gusts as high as 85 mph. Larry’s hurricane-force wind likely will produce blizzard conditions across Greenland, although Larry might lose the tropical aspects of a hurricane by then.
The term extratropical has to do with the storm’s core. A hurricane has a warm core, while an extratropical (or post-tropical) has a cold core.
Cold core systems produce weather features like cold fronts and warm fronts — terms people are more familiar with. Warm core systems produce weather features such as eyes, eyewalls and outer-bands.
As Larry interacts with this other system, it will be able to pull in a tremendous amount of moisture leading to significant snowfall in Greenland.
Widespread totals of 12 to 18 inches are expected in the eastern half of the island nation. Higher elevations along the east coast could get 2 to 4 feet or higher.
Landfall as a hurricane in Canada first
In the short term, Larry will bring affect the US and Canada before Greenland.
While Larry is expected to gradually weaken Friday as it moves through the colder waters of the northern Atlantic, it is still expected to retain hurricane strength until it passes Newfoundland.
Damaging winds, dangerous storm surge and heavy rainfall also are expected in Newfoundland.
What makes Larry interesting is that it may be able to make landfall in Canada before transitioning to extratropical. Landfall is expected late Friday night or early Saturday morning in Newfoundland and Labrador. It is forecast to be a Category 1 hurricane.
Larry is a large hurricane with hurricane-force winds extending outward up to 90 miles from the center. Even after it transitions to extratropical, Larry is expected to stay big in size.
The Canadian Hurricane Centre has extended the Tropical Storm Warning along the southern coast of southeastern Newfoundland westward to Francois and along the northern coast of southeastern Newfoundland to Fogo Island.
