DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of the large eye of Hurricane
Larry was located by an Air Force Reserve Hurricane Hunter aircraft
near latitude 25.8 North, longitude 56.8 West. Larry is moving
toward the northwest near 12 mph (19 km/h), and this general motion
is expected to continue through Wednesday.  A turn toward the
north-northwest and north with an increase in forward speed is
forecast on Thursday.  On the forecast track, the center of Larry
should pass east of Bermuda on Thursday.
 
Data from the Hurricane Hunter aircraft indicate that maximum 
sustained winds remain near 115 mph (185 km/h) with higher gusts.  
Larry is a category 3 hurricane on the Saffir-Simpson Hurricane Wind 
Scale.  Slow weakening is forecast during the next several days.
 
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 minimum central pressure recently reported by the reconnaissance 
aircraft is 967 mb (28.56 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Larry can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.
 
WIND:  Tropical storm conditions are possible on Bermuda beginning
late Wednesday or early Thursday.
 
SURF:  Swells generated by Larry will continue to affect the Lesser
Antilles, portions of the Greater Antilles, and the Bahamas through
midweek, and impact Bermuda through the end of the week. Significant
swells should reach the east coast of the United States and Atlantic
Canada by midweek and continue affecting these shores through the
end of the week.  These swells are likely to cause life-threatening
surf and rip current conditions.  Please consult products from your
local weather office.
