SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * The Papahanaumokuakea Marine National Monument from Nihoa to French Frigate Shoals A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. A Hurricane Watch may be required for additional portions of the Papahanaumokuakea Marine National Monument later today. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM HST (2100 UTC), the center of Hurricane Nolo was located near latitude 17.7 North, longitude 163.1 West. Nolo is moving toward the west-northwest near 12 mph (19 km/h). A turn toward the northwest is forecast later today, with a turn toward the north expected on Tuesday. On the forecast track, the center of Nolo will remain well southwest and west of the main Hawaiian Islands but will approach the Papahanaumokuakea Marine National Monument on Tuesday. Maximum sustained winds are near 145 mph (230 km/h) with higher gusts. Nolo is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. A gradual weakening trend is likely to begin tonight, followed by faster weakening through the middle of the week. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 150 miles (240 km). The estimated minimum central pressure is 933 mb (27.55 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected in the Hurricane Warning area in the Papahanaumokuakea Marine National Monument by Wednesday, with tropical storm conditions likely by Tuesday. RAINFALL: Outer bands east of Nolos track will produce 3 to 6 inches of rain across Kauai and Niihau between Tuesday and Thursday. This rainfall could produce areas of flooding and mudslides, especially in areas of steep terrain. SURF: Swells generated by Nolo will affect south- and west-facing shores of the main Hawaiian Islands for the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Large surf associated with Nolo will affect the Papahanaumokuakea Marine National Monument beginning later today. These large waves will likely inundate some of the low-lying atolls, especially from French Frigate Shoals to Nihoa. Please consult products from your local weather office.
