DISCUSSION AND OUTLOOK
----------------------
At 500 AM AST (0900 UTC), the large eye of Hurricane Larry was 
located near latitude 26.5 North, longitude 57.3 West. Larry is 
moving toward the northwest near 10 mph (17 km/h), and this general 
motion is expected to continue through today.  A turn toward the 
north-northwest and north with an increase in forward speed is 
forecast on Thursday.  A faster northeastward motion is expected 
by Friday. On the forecast track, the center of Larry should pass 
east of Bermuda on Thursday. 
 
Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts.  Larry is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Gradual weakening is forecast during the 
next several days, but Larry is expected to remain a hurricane 
during that time. 
 
Larry is a large hurricane. Hurricane-force winds extend outward up 
to 70 miles (110 km) from the center and tropical-storm-force winds 
extend outward up to 185 miles (295 km).
 
The estimated minimum central pressure is 967 mb (28.56 inches).
