DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Hurricane Larry was located
near latitude 46.8 North, longitude 54.9 West. Larry is moving
toward the north-northeast near 47 mph (76 km/h).  A very rapid 
motion toward the north-northeast or northeast is expected through 
Saturday night.  On the forecast track, the center of Larry will 
be moving across southeastern Newfoundland during the next few 
hours.
 
Maximum sustained winds are near 80 mph (130 km/h) with higher
gusts.  Little change in strength is forecast before landfall in 
Newfoundland.  After landfall, Larry is expected to become a strong 
extratropical low by Saturday 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).  A station at Cape St. Mary's, Newfoundland, 
relayed by amateur radio, recently reported sustained winds of    
84 mph (135 km/h) and a wind gust of 97 mph (156 km/h) at an 
unknown elevation.
 
The estimated minimum central pressure is 958 mb (28.29 inches).
