DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Hurricane Larry was located
near latitude 40.0 North, longitude 60.5 West. Larry is moving
quickly toward the north-northeast near 29 mph (46 km/h).  An even 
faster north-northeast to northeast motion is expected during the 
next day or two.  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 80 mph (130 km/h) with higher
gusts.  Little change in strength is expected before landfall in 
Newfoundland.  After landfall, Larry should weaken and become an 
extratropical cyclone on Saturday before it merges with another low 
over the Labrador Sea on Sunday.
 
Larry is a large tropical cyclone.  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 971 mb (28.68 inches).
