How Storm Larry socked Greenland and unleashed an unusual blizzard

The massive storm trucked copious tropical moisture onto the eastern side of the island — rare for this time of the year

Hurricane Larry put on a show in the Atlantic, sideswiping Bermuda before charging into Newfoundland. Its final act wasn’t so much wet as it was white, however. The intrepid and long-lived storm delivered significant snow to Greenland on Sunday and Monday — an unusual occurrence so soon after the summer melt season ended.

“It definitely added a substantial amount of snow to southeastern Greenland,” Lauren Andrews, a NASA glaciologist, wrote in an email. “I don’t think we can be sure as to whether it cancels out all or part of the summer melt yet.”

The satellite images above show the change in snow cover near the Timmiarmiut Fjord between Sept. 5 and 14, primarily because of Larry.

Larry first developed on Aug. 31 from a tropical wave that had exited the coast of Africa near Senegal. It trekked west across the Atlantic’s “main development region,” commonly referred to as “Hurricane Alley,” before strengthening into a hurricane early on Sept. 2. It rapidly intensified and became a major hurricane with Category 3 winds by that evening. The Bermuda Weather Service issued a tropical storm warning on Sept. 8, and Larry fringed the island with gusty winds and choppy seas shortly thereafter — but its rain shield stayed entirely offshore.
