At 500 PM AST (2100 UTC), the center of Hurricane Sam was located
near latitude 35.4 North, longitude 58.2 West. Sam is moving toward
the northeast near 17 mph (28 km/h). This general track with an

Newfoundland over the North Atlantic.
 
Maximum sustained winds have decreased to near 125 mph (205 km/h) 
with higher gusts.  Sam is a category 3 hurricane on the 
Saffir-Simpson Hurricane Wind Scale.  Further slow weakening is 
anticipated during the next few days, and Sam could transition into 
a powerful post-tropical cyclone on Tuesday.
 
Sam is a large tropical cyclone. Hurricane-force winds extend 
outward up to 70 miles (110 km) from the center and 
tropical-storm-force winds extend outward up to 240 miles (390 km).
