SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Watch is in effect for... * Hawaii County. A Hurricane Watch means that hurricane conditions are possible within the watch area. A Hurricane Watch is typically issued 48 hours before the anticipated first occurrence of tropical storm force winds, conditions that make outside preparations difficult or dangerous. Interests elsewhere in the main Hawaiian Islands should monitor the progress of Madeline. Watches may be required for additional Hawaiian Islands later tonight or tomorrow. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 200 AM HST (1200 UTC), the center of Hurricane Madeline was located near latitude 19.3 North, longitude 147.7 West. Madeline is moving toward the west near 9 mph (15 km/h) and this motion is expected to become west southwesterly late today through early Thursday. On the forecast track, the center of Madeline will pass dangerously close to the Big Island Wednesday and Wednesday night. Maximum sustained winds are near 130 mph (215 km/h) with higher gusts. Madeline is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some weakening is forecast through early Thursday. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). The estimated minimum central pressure is 950 mb (28.06 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are possible over Hawaii County on Wednesday. SURF: Swells generated by Madeline are expected to reach the Hawaiian Islands over the next couple of days, possibly becoming damaging along some coastlines Wednesday and Thursday. RAIN: Heavy rains associated with Madeline may reach Hawaii County on Wednesday, and may impact other Hawaiian Islands later Wednesday into Friday.
