At 1100 am HST, 2100 UTC, the center of hurricane Ana was located near latitude 16.4 north, longitude 155.2 west. Ana is moving toward the west-northwest near 14 mph, 22 km/h. A slight turn to the northwest is expected today and Saturday. A decrease in forward speed is expected Saturday night and Sunday. On this forecast track, the center of Ana will pass about 115 miles southwest of the Big Island tonight and about 115 miles southwest of the rest of the main Hawaiian islands this weekend.

Maximum sustained winds are near 75 mph, 120 km/h, with higher gusts. Some additional strengthening is expected today, followed by gradual weakening late Saturday and Sunday.

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 eastern end of the main Hawaiian island chain today through Saturday. These large swells will continue to spread up the island chain through the weekend. Surf produced by these swells could potentially be damaging along exposed south and southeast shorelines beginning later today and Saturday, and persisting through the weekend in some areas.

RAINFALL

Heavy rainfall associated with Ana may reach the Big Island of Hawaii this afternoon, with total rain accumulations between 6 and 8 inches expected, with 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.
