GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) showed Hurricane Larry as it made landfall in Newfoundland at 0345 UTC on 11 September 2021 (causing wind gusts to 73 knots at Cape Race and 78 knots at St. Johns) — maintained hurricane intensity until 1500 UTC over the Labrador Sea — then was quickly absorbed by a large extratropical low as it progressed toward the southeast coast of Greenland on 12 September. Along the coast of Greenland, the merged remnants of Larry caused wind gusts to 63 knots at Narsarsuaq and 88 knots at Kulusuk.
