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 Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Additional watches and warnings may be required for additional portions of the Papahanaumokuakea Marine National Monument later this week. 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 21.3 North, longitude 164.2 West. Nolo is moving toward the north near 8 mph (13 km/h). On the forecast track, the center of Nolo will remain well southwest and west of the main Hawaiian Islands. Nolo will continue to move northward across the Papahanaumokuakea Marine National Monument today. On Wednesday, Nolo will slow significantly and turn toward the west, then continue generally westward through the latter part of the week. Maximum sustained winds are near 100 mph (155 km/h) with higher gusts. Steady weakening is forecast over the next couple of days, followed by some re-intensification during the latter part of this week. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). The estimated minimum central pressure is 971 mb (28.68 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 ongoing. Tropical storm conditions are possible in the Tropical Storm Watch area in the Papahanaumokuakea Marine National Monument by Thursday. RAINFALL: Outer bands east of Nolos track will produce 3 to 6 inches of rain across Kauai and Niihau through Thursday. This rainfall could produce areas of flooding and mudslides, especially in areas of steep terrain. For a complete depiction of forecast rainfall associated with Nolo, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_cp2.shtml?rainqpf 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 continue to affect the Papahanaumokuakea Marine National Monument over the next several days. 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.
