DISCUSSION AND OUTLOOK ---------------------- At 1100 PM HST (0900 UTC), the center of Hurricane Douglas was located near latitude 22.5 North, longitude 158.8 West. Douglas is moving toward the west-northwest near 16 mph (26 km/h). This general motion is expected to continue for the next couple of days, with a slight turn to the west and an increase in forward speed. Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Weakening is forecast during the next 48 hours, but Douglas will remain a hurricane until it passes west of Kauai. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 115 miles (185 km). The estimated minimum central pressure is 987 mb (29.15 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected across northern portions of Kauai 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. RAINFALL: Rainfall associated with Douglas is expected to affect portions of the main Hawaiian Islands into Monday. Total rain accumulations of 3 to 6 inches with locally higher amounts are possible, with the greatest rainfall in elevated terrain on Kauai. 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. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM HST.
