A warning is typically issued\n36 hours before the anticipated first occurrence of\ntropical-storm-force winds, conditions that make outside\npreparations difficult or dangerous.

Lowell is moving\ntoward the north-northwest near 6 mph (9 km/h). A turn toward the \nnorth and north-northeast with an increase in forward speed is \nexpected over the next couple of days, bringing the center of \nLowell across portions of the Papahanaumokuakea Marine National \nMonument, just west of the main Hawaiian Islands, Monday night. \nLowell is forecast to turn toward the north-northwest and slow \ndown by Tuesday night after passing the Hawaiian Islands.\n \nMaximum sustained winds are near 125 mph (205 km/h) with higher\ngusts.  Lowell is a category 3 hurricane on the Saffir-Simpson\nHurricane Wind Scale.  Some fluctuations in intensity remain \npossible through this afternoon, followed by gradual weakening \nbeginning tonight. Lowell is expected to remain a major hurricane \nthrough Monday.\n \nHurricane-force winds extend outward up to 50 miles (85 km) from the\ncenter and tropical-storm-force winds extend outward up to 175 miles\n(280 km).\n \nThe estimated minimum central pressure is 943 mb (27.85 inches).\n \n \nHAZARDS AFFECTING LAND\n----------------------\nKey messages for Lowell can be found in the Tropical Cyclone\nDiscussion under AWIPS header HFOTCDCP4 and WMO header WTPA44\nPHFO.\n \nWIND: Tropical storm conditions are expected in Kauai County by\nMonday afternoon or evening. Hurricane conditions are possible in\nin the Papahanaumokuakea Marine National Monument between Nihoa and\nFrench Frigate Shoals Monday night, with tropical storm conditions\nbeginning Monday afternoon. Wind speeds atop and on the windward \nand leeward sides of hills and mountains are often up to 30 percent \nstronger than the near-surface winds, and in some elevated locations \ncould be even greater.\n \nRAINFALL: Hurricane Lowell is expected to produce rainfall totals of \n6 to 10 inches for Kauai, with maximum totals of 14 inches possible. \nFor the Big Island, 4 to 8 inches of rain is expected with isolated \ntotals of 12 inches possible. For Maui, 2 to 4 inches of rain is \nexpected, with isolated maximum totals of 8 inches possible. Across \nthe remaining islands, rainfall of 2 to 4 inches is possible. This \nrainfall may produce significant flash flooding and mudslides, \nespecially across Kauai County and portions of the Big Island.\n\nFor a complete depiction of forecast rainfall associated with \nHurricane Lowell, please see the National Weather Service Storm \nTotal Rainfall Graphic available at \nhurricanes.gov/graphics_ep12.shtml?rainqpf\n \nSTORM SURGE: The combination of storm surge and tide will cause\nnormally dry areas near the coast to be flooded by rising waters\nmoving inland from the shoreline. The water could reach the\nfollowing heights above ground somewhere in the indicated areas if\nthe peak surge occurs at the time of high tide...\n \nKauai County...1-3 ft\nOahu...Up to 1 ft\n \nThe deepest water will occur along the immediate coast near and to\nthe right of the center, where the surge will be accompanied by\nlarge and destructive waves. Surge-related flooding depends on the\nrelative timing of the surge and the tidal cycle, and can vary\ngreatly over short distances.\n \nFor a complete depiction of areas at risk of storm surge inundation,\nplease see the National Weather Service Peak Storm Surge Graphic,\navailable at hurricanes.gov/graphics_cp4.shtml?peakSurge.\n \nSURF: Swells from Lowell are likely to cause life-threatening surf\nand rip current conditions during the next several days across\nmany of the Hawaiian islands.
