DISCUSSION AND OUTLOOK
----------------------
At 500 AM HST (1500 UTC), the center of Hurricane Hector was located
near latitude 17.7 North, longitude 165.9 West.  Hector is moving
toward the west-northwest near 16 mph (26 km/h), and this motion is
expected to continue today.  Hector is expected to turn toward the
northwest from tonight through Saturday night.  This forecast track
keeps Hector's wind field far away from Johnston Island.
 
Maximum sustained winds are near 130 mph (215 km/h) with higher
gusts.  Hector is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  There may be slight fluctuations in intensity
today and tonight, but Hector will likely remain a powerful
hurricane.  Some gradual weakening is expected from Saturday through
Saturday night.
 
Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 110 miles
(175 km).
