DISCUSSION AND OUTLOOK
----------------------
At 800 AM AST (1200 UTC), the center of Hurricane Larry was located 
near latitude 39.2 North, longitude 60.8 West. Larry is moving 
quickly toward the north-northeast near 26 mph (43 km/h). A turn to 
the northeast with an increase in forward speed is expected later 
today.  On the forecast track, the center of Larry will pass well 
southeast of Nova Scotia today, and move over southeastern 
Newfoundland tonight.
 
Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts.  Gradual weakening is forecast during the next day or so, but
Larry is expected to remain a hurricane until it passes
Newfoundland.  Larry should become an extratropical cyclone on
Saturday, and is now forecast to be absorbed by a larger
extratropical low near Greenland by the end of the weekend.
 
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 240 miles (390 km).
 
The estimated minimum central pressure is 968 mb (28.59 inches).
