DISCUSSION AND 48-HOUR OUTLOOK

At 500 pm HST, 0300 UTC, the center of hurricane Ana was located near latitude 17.0 north, longitude 156.6 west. Ana is moving toward the northwest near 13 mph, 20 km/h. A continued turn to the northwest is expected tonight and Saturday. A decrease in forward speed is expected Saturday night and Sunday. On this forecast track, the center of Ana will pass about 150 miles southwest of the Big Island tonight and about 175 miles southwest of the rest of the main Hawaiian islands this weekend.

Maximum sustained winds are near 80 mph, 130 km/h, with higher gusts. Some additional strengthening is possible through tonight, followed by gradual weakening late Saturday and Sunday.

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 986 mb, 29.12 inches.

HAZARDS AFFECTING LAND

WIND

Tropical storm conditions are possible on the Big Island of Hawaii tonight. Tropical storm conditions are possible across the rest of the main Hawaiian islands during the weekend.

SURF

Large swells produced by Ana are expected to build over the main Hawaiian island chain through Saturday. These large swells will continue to spread up the island chain through Saturday. Surf produced by these swells could potentially be damaging along exposed south and southeast shorelines through Sunday, though surf will diminish earlier on the Big Island.

RAINFALL

Heavy rainfall associated with Ana may reach the Big Island of Hawaii late this afternoon, with total rain accumulations between 6 and 8 inches expected and isolated totals of 12 inches possible. Heavy rain could potentially affect the other islands Saturday and Sunday. This rainfall could cause life-threatening flash floods and mud slides.
