At 200 AM AST (0600 UTC), the center of Hurricane Larry was located
near latitude 48.7 North, longitude 53.2 West. Larry is moving
toward the north-northeast near 47 mph (76 km/h).  A very rapid

be moving quickly away from Newfoundland during the next several 
hours.
 
Maximum sustained winds remain near 80 mph (130 km/h) with higher

expected to become a strong extratropical low later this morning 
before it merges with another low over the Labrador Sea on Sunday.
 
Hurricane-force winds extend outward up to 105 miles (165 km) from
the center and tropical-storm-force winds extend outward up to 255
miles (405 km).  St. John's International Airport, Newfoundland, 
recently reported sustained winds of 60 mph (96 km/h) and a wind 
gust of 90 mph (144 km/h).
