SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. Interests in the Hawaiian Islands should closely monitor the progress of this system. Watches may be required for portions of the Papahanaumokuakea Marine National Monument later today. DISCUSSION AND OUTLOOK ---------------------- At 500 AM HST (1500 UTC), the eye of Hurricane Nolo was located by Air Force Reconnaissance aircraft near latitude 16.2 North, longitude 158.3 West. Nolo is moving toward the west near 12 mph (19 km/h). A turn toward the northwest is expected by tonight, 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 but will approach the Papahanaumokuakea Marine National Monument early this week. Maximum sustained winds have increased to near 105 mph (165 km/h) with higher gusts. Nolo is predicted to strengthen into a major hurricane within the next day or so and reach its peak intensity by Monday. Weakening is expected in a couple of days. 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 the main Hawaiian Islands through today, although the core winds of Nolo will stay to the south. RAINFALL: Rainfall and flooding threats are diminishing across the Big Island today with only scattered showers expected. For the eastern and southern portions of the Big Island, up to an additional inch of rainfall is possible. Across the remainder of the Hawaiian Islands, no significant precipitation is expected. 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.
