At 800 PM AST (0000 UTC), the center of the large eye of Hurricane 
Larry was located  by an Air Force Reserve Hurricane Hunter aircraft
near latitude 25.4 North, longitude 56.5 West. Larry is moving

forecast on Thursday.  On the forecast track, the center of Larry
should pass east of Bermuda on Thursday.

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.

up to 70 miles (110 km) from the center and tropical-storm-force

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
