DISCUSSION AND OUTLOOK

----------------------

At 800 PM HST (0600 UTC), the center of Hurricane Douglas was located by Hurricane Hunter aircraft near latitude 22.2 North, longitude 158.0 West. Douglas is moving toward the west-northwest near 16 mph (26 km/h), and this motion is expected to continue over the next couple of days. On the forecast track, Douglas will pass near Oahu and Kauai tonight.

Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Gradual weakening is forecast during the next 48 hours, but Douglas is expected to remain a hurricane as it moves near Kauai

later tonight.

Hurricane-force winds extend outward up to 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 115 miles (185 km).

The estimated minimum central pressure is 988 mb (29.18 inches).

HAZARDS AFFECTING LAND

----------------------

WIND: Hurricane conditions are expected across portions of Oahu this evening, and on Kauai later tonight. Due to the steep terrain of the islands, localized strong wind gusts are expected.

SURF: Large swells generated by Douglas will affect the Hawaiian Islands tonight, producing life-threatening and potentially damaging surf along exposed shores. Storm surge of up to 2 feet is

possible. Surf will decline on Monday.

RAINFALL: Heavy rainfall associated with Douglas is expected to affect portions of the main Hawaiian Islands tonight into Monday. Total rain accumulations of 3 to 6 inches with locally higher amounts are possible, with the greatest rainfall in elevated terrain. This rain may result in flash flooding and land slides, as well as rapid water level rises on small streams.

Key messages for Douglas can be found in the Tropical Cyclone Discussion under AWIPS header HFOTCDCP2 and WMO header WTPA32 PHFO.
