“Secure loose objects on your property and anticipate power interruptions. “These winds will likely topple some trees (leading to downed utility lines), damage signs and cause some property damage to roofing materials, cladding, fences and exterior fixtures,” the Canadian Hurricane Centre cautioned. 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.ĭamaging winds, dangerous storm surge and heavy rainfall also are expected in Newfoundland. These swells are likely to cause life-threatening surf and rip current conditions.” said the National Hurricane Center. “Significant swells from Larry will continue affecting Bermuda, the east coast of the United States, and Atlantic Canada through Saturday. In the short term, Larry will bring affect the US and Canada before Greenland. So did Superstorm Sandy, which also helped produce snowfall in October 2012. What makes Larry a bit more unusual is the timing. In fact, just last year Hurricane Zeta brought snow to the Northeast US, including several inches to Massachusetts. While it is rare for tropical systems to help trigger snow, it’s not unheard of. Hurricane Larry could bring feet of snow to Greenland. Higher elevations along the east coast could get 2 to 4 feet or higher. Widespread totals of 12 to 18 inches are expected in the eastern half of the island nation. Warm core systems produce weather features such as eyes, eyewalls and outer-bands.Īs Larry interacts with this other system, it will be able to pull in a tremendous amount of moisture leading to significant snowfall in Greenland. A hurricane has a warm core, while an extratropical (or post-tropical) has a cold core.Ĭold core systems produce weather features like cold fronts and warm fronts – terms people are more familiar with. The term extratropical has to do with the storm’s core. “Larry should become an extratropical cyclone on Saturday, and is now forecast to be absorbed by a larger extratropical low near Greenland by the end of the weekend,” the National Hurricane Center says. Larry’s hurricane-force wind likely will produce blizzard conditions across Greenland, although Larry might lose the tropical aspects of a hurricane by then. When it gets there, it will have sustained winds around 60 to 70 mph, with gusts as high as 85 mph. Hurricane Larry is forecast to slide up the east coast of Greenland this weekend. AccuWeather’s team of tropical weather experts, led by veteran meteorologist Dan Kottlowski, predicts that the 2021 Atlantic hurricane season will result in 16-20 named storms, including seven. They do not represent the total possible ranges of activity seen in past similar years. June 1 is two months away, but troubling signs are already emerging about what lies ahead for the 2021 Atlantic basin hurricane season. Hurricane-force winds are not uncommon in Greenland, but hurricanes that bring significant snow are. The seasonal activity is expected to fall within these ranges in 7 out of 10 seasons with similar climate conditions and uncertainties to those expected this year.
