DISCUSSION AND 48-HOUR OUTLOOK

At 100 am HST, 1100 UTC, the center of hurricane Ana was located near latitude 20.3 north, longitude 159.5 west. Ana is moving toward the northwest near 6 mph, 9 km/h, and this motion is expected to continue overnight. A turn toward the west-northwest is expected on Sunday, followed by a gradual turn back toward the northwest on Monday. On this forecast track, the center of Ana will pass about 105 miles southwest of Kauai early Sunday morning, 75 miles south of Niihau Sunday morning, about 135 miles south of Nihoa Sunday night, and about 85 miles southwest of necker island Monday night.

Maximum sustained winds are near 80 mph, 130 km/h, with higher gusts. Some weakening is forecast during the next 48 hours, and Ana may weaken to a tropical storm over the next couple of days.

Hurricane force winds extend outward up to 25 miles, 35 km, from the center, and tropical storm force winds extend outward up to 105 miles, 165 km.

The estimated minimum central pressure is 989 mb, 29.21 inches.
