DISCUSSION AND OUTLOOK ---------------------- At 1100 PM HST (0900 UTC), the center of Hurricane Nolo was located near latitude 16.5 North, longitude 157.3 West. Nolo is moving toward the west near 9 mph (15 km/h) and this general motion is expected to continue through Sunday. A turn toward the northwest is expected Sunday night, with this general motion continuing through Tuesday. On the forecast track, the center of Nolo will remain well south and southwest of the main Hawaiian Islands. Maximum sustained winds have increased to near 100 mph (155 km/h) with higher gusts. Nolo is predicted to strengthen into a major hurricane on Sunday or Sunday night and reach its peak intensity by Monday. Weakening is expected thereafter. 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 967 mb (28.56 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Nolo can be found in the Tropical Cyclone Discussion under AWIPS header HFOTCDCP2 and WMO header WTPA42 PHFO. WIND: Strong and gusty winds are possible for all of the Hawaiian Islands through the weekend, although the core winds of Nolo will stay to the south. RAINFALL: For the eastern and southern portions of the Big Island, Nolo will produce additional rainfall totals 1 to 2 inches, with isolated maximum amounts of 4 inches. Storm totals through Sunday will range between 10 and 15 inches with isolated maximum amounts of 20 inches. Additional areas of flooding and mudslides will be possible, especially in areas of steep terrain. For the western portions of the Big Island, rainfall totals of an inch or less are expected. For eastern Maui, additional rainfall totals of 1 to 2 inches are expected, bringing storm totals to 4 to 8 inches. Additional areas of flooding and mudslides will be possible, especially in areas of steep terrain. For a complete depiction of forecast rainfall associated with Hurricane Nolo, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_cp2.shtml?rainqpf STORM SURGE: The threat of significant storm surge has diminished, yet water levels along the coast will remain elevated through upcoming tide cycles due to persistent, dangerous wave action. SURF: Swells generated by Nolo are affecting exposed east- and south-facing shores of the Big Island and are expected to spread westward and build through the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
