At 1100 PM HST (0900 UTC), the center of Hurricane Douglas was
located near latitude 15.7 North, longitude 140.3 West. Douglas is
moving toward the west-northwest near 18 mph (30 km/h), and this

forecast track Douglas will approach the Hawaiian Islands Saturday
night, and be near those Islands on Sunday.
 
Maximum sustained winds are near 130 mph (215 km/h) with higher 
gusts.  Douglas is a category 4 hurricane on the Saffir-Simpson 
Hurricane Wind Scale.  Gradual weakening is expected to begin on 
Friday and continue through the weekend.  Douglas is forecast to be 
near hurricane strength when it approaches the Hawaiian Islands.
 
Hurricane-force winds extend outward up to 30 miles (45 km) from the

(150 km).
 
The estimated minimum central pressure is 954 mb (28.17 inches).
