Lowell is then forecast to turn toward the northwest and west and slow down on Wednesday and Thursday after passing the main Hawaiian Islands. Maximum sustained winds have decreased to near 80 mph (130 km/h) with higher gusts. Further weakening is forecast, and Lowell should become a tropical storm later today and continue to weaken for the next couple of days. Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm-force winds extend outward up to 230 miles (370 km). The estimated minimum central pressure is 972 mb (28.71 inches).
