Hurricane Larry Discussion Number  43
NWS National Hurricane Center Miami FL       AL122021
500 AM AST Sat Sep 11 2021
 
Larry made landfall near South East Bight, Newfoundland, around 0345
UTC.  Since then, the hurricane has moved quickly north-
northeastward at 42 kt and is now well northeast of Newfoundland.
Although the hurricane still has some central convection, the low-
and mid-level centers are separating, and the remaining convection
is decreasing.  The initial winds are lowered to 65 kt, consistent
with the degraded structure.  Larry should quickly transition into
a strong post-tropical cyclone later today while it continues its
speedy north-northeastward course, then dissipate as it merges with
a developing mid-latitude low over the Labrador Sea.  No
significant changes were made to the track or intensity forecasts.
 
 
Key Messages:
 
1. Large swells generated by Larry will continue to affect the
Bahamas, Bermuda, the east coast of the United States, and
Atlantic Canada through tonight. These swells will cause
life-threatening surf and rip current conditions, and beachgoers
and other interests along these coasts are urged to follow the
guidance of lifeguards and local officials.
