DISCUSSION AND OUTLOOK
----------------------
At 500 AM HST (1500 UTC), the center of Hurricane Hector was located
near latitude 19.3 North, longitude 170.1 West. Hector is moving
toward the west-northwest near 12 mph (19 km/h). While this general
motion is expected over the next couple of days, a slight turn
toward the northwest with an increase in forward speed is expected
later today. 
 
Maximum sustained winds are near 120 mph (195 km/h) with higher
gusts.  Hector is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Steady weakening is forecast over the next
day or two, with a slower rate of weakening expected
thereafter. 
 
Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 140 miles
(220 km).
 
The estimated minimum central pressure is 957 mb (28.26 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
SURF:  Large north swells generated by Hector will gradually
decline on Johnston Island today. Hector is producing swell
that will begin to arrive over portions of the Northwestern Hawaiian
Islands today, and continue for the next couple of days. The large
southeast seas and swells will peak between Maro Reef and Lisianski
Island tonight and Sunday, and across Pearl and Hermes, Midway Atoll
and Kure Atoll late Sunday into Monday.
 
WIND:  Tropical Storm conditions are possible across Lisianski
Island and Pearl and Hermes Atoll on Sunday.
