DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 AM HST (1500 UTC), the center of Hurricane Madeline was located near latitude 18.9 North, longitude 153.1 West. Madeline is moving toward the west near 14 mph (22 km/h) and this general motion is expected to continue for the next couple of days. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. Steady weakening is forecast during the next 48 hours, and Madeline is forecast to weaken to a tropical storm tonight or Thursday. Hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). The estimated minimum central pressure is 988 mb (29.18 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected to develop over Hawaii County later today, continuing into early Thursday. Tropical storm conditions are expected to develop over Maui County later today, continuing into early Thursday. SURF: Swells generated by Madeline are expected to increase in Hawaiian waters today, possibly becoming damaging along east facing shores of Hawaii County and the Island of Maui today and tonight. RAIN: Madeline is expected to produce total rain accumulations of 5 to 10 inches, with isolated maximum amounts near 15 inches, across Hawaii County, especially over windward portions. Total rainfall accumulations of 1 to 3 inches, with isolated maximum amounts up to 4 inches, can be expected in the islands of Maui County. This rainfall may lead to dangerous flash floods and mudslides. STORM SURGE: Depending on the track of Madeline, the combination of storm surge and tides could cause normally dry areas near the coast to become flooded. The water could reach 1 to 3 feet above ground if peak surge were to coincide with high tide. The surge would be accompanied by large damaging surf and can vary over short distances.
