DISCUSSION AND OUTLOOK
----------------------
At 500 AM AST (0900 UTC), the center of Hurricane Sam was located 
near latitude 15.2 North, longitude 51.4 West.  Sam is moving toward 
the northwest near 8 mph (13 km/h).  This general motion is expected 
to continue for the next several days, with an increase in forward 
speed beginning on Thursday.

Maximum sustained winds are near 130 mph (215 km/h) with higher 
gusts.  Sam is a category 4 hurricane on the Saffir-Simpson 
Hurricane Wind Scale.  Little change in strength is expected during 
the next day or so.  Thereafter, some slow weakening is forecast 
through midweek, although Sam should remain a major hurricane.

Sam is a small hurricane.  Hurricane-force winds extend outward up 
to 30 miles (45 km) from the center and tropical-storm-force winds 
extend outward up to 105 miles (165 km).

The estimated minimum central pressure is 952 mb (28.12 inches).


HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Sam will reach the Lesser Antilles today
and impact these islands for the next several days.  These swells
could cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
