DISCUSSION AND OUTLOOK ---------------------- At 1100 PM HST (0900 UTC), the center of Tropical Storm Nolo was located near latitude 22.4 North, longitude 164.6 West. Nolo is moving toward the west-northwest near 6 mph (9 km/h). Nolo is moving west-northwestward across the Papahanaumokuakea Marine National Monument and is expected to turn westward overnight or early Wednesday. A generally westward motion is expected through the latter part of the week. Maximum sustained winds have decreased to near 70 mph (110 km/h) with higher gusts. Further weakening is forecast over the next day or so, followed by some re-intensification during the latter part of this week. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 987 mb (29.15 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected within the Tropical Storm Warning area from Nihoa to French Frigate Shoals overnight through Wednesday. Tropical storm conditions are possible within the Tropical Storm Watch area from French Frigate Shoals to Maro Reef 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.
