 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.
