DISCUSSION AND OUTLOOK
----------------------
At 200 PM HST (0000 UTC), the eye of Hurricane Hector was located
near latitude 16.4 North, longitude 150.0 West. Hector is moving
toward the west near 17 mph (27 km/h), and this general motion is
expected to continue through Thursday. On the forecast track, the
center of Hector is expected to pass less than 200 miles south of
the Big Island on Wednesday. Remember, the effects of a hurricane
are far-reaching and can extend well away from the center.
 
Data from the Air Force Reserve Hurricane Hunters indicate
maximum sustained winds remain near 130 mph (215 km/h) with
higher gusts.  Hector is still a category 4 hurricane on the
Saffir-Simpson Hurricane Wind Scale.  Some weakening is forecast
over the next couple of days.
 
Hurricane-force winds extend outward up to 40 miles (65 km) from
the center and tropical-storm-force winds extend outward up to 115
miles (185 km).
 
The estimated minimum central pressure is 952 mb (28.11 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Hector are expected to reach southeast
and east facing shores of the Big Island and eastern Maui late
today, likely becoming large and dangerous by late tonight and
Wednesday.
 
WIND:  Tropical storm conditions are possible across portions of
Hawaii County on Wednesday as the core of Hector passes south of
the Big Island.
