DISCUSSION AND OUTLOOK
----------------------
At 800 PM AST (0000 UTC), the center of Hurricane Larry was located 
near latitude 34.2 North, longitude 62.3 West.  Larry is moving 
toward the north near 21 mph (34 km/h). A further increase in 
forward speed is expected tonight, with an even faster northeastward 
motion forecast by Friday.  On the forecast track, the center of 
Larry will continue to move away from Bermuda tonight, and move near 
or over southeastern Newfoundland Friday night or early Saturday 
morning.
 
Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts.  Gradual weakening is forecast to begin on Friday, but Larry
is expected to remain a hurricane until it passes Newfoundland.
Larry should become an extratropical cyclone on Saturday, then
weaken further while it passes southeast of Greenland Sunday night.
Larry is expected to be absorbed by a larger extratropical low east
of Greenland by Monday.
 
Larry is a large hurricane.  Hurricane-force winds extend outward
up to 90 miles (150 km) from the center and tropical-storm-force
winds extend outward up to 220 miles (350 km).  Pearl Island,
Bermuda, reported sustained winds of 39 mph (63 km/h) with a gust to
45 mph (74 km/h).
 
The estimated minimum central pressure is 966 mb (28.53 inches).
