Lowell is \nmoving toward the north-northeast near 18 mph (30 km/h). A motion \ntoward the north-northeast and north at a similar forward speed is \nforecast through Tuesday. The core of Lowell is expected to pass \nnear or just west of Niihau overnight into early Tuesday. Then, \nLowell is forecast to turn toward the northwest and west and slow \ndown on Wednesday and Thursday after passing the Hawaiian Islands.\n \nMaximum sustained winds are near 110 mph (175 km/h) with higher\ngusts. Lowell will remain a powerful hurricane while passing near \nthe Hawaiian Islands overnight into early Tuesday, and then \nweakening is expected over the next several days.\n \nHurricane-force winds extend outward up to 70 miles (110 km) from\nthe center and tropical-storm-force winds extend outward up to 195\nmiles (315 km). Barking Sands (PHBK) on western Kauai recently\nreported sustained winds of 51 mph (82 km/h) with a gust to 84 mph\n(135 km/h). Lihue Airport (PHLI) along the southeastern coast of\nKauai recently reported sustained winds of 53 mph (85 km/h) with a\ngust to 79 mph (127 km/h). Daniel K Inouye International Airport\n(PHNL) in Honolulu recently reported a gust of 45 mph (72 km/h).\n \nThe estimated minimum central pressure based on aircraft data is \n963 mb (28.44 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: Hurricane conditions are spreading across portions of Kauai\nCounty. Wind speeds atop and on the windward and leeward sides of\nhills and mountains are often up to 30 percent stronger than the\nnear-surface winds. Tropical storm conditions, especially in gusts,\nare occurring on Oahu.\n \nTropical storm conditions are ongoing in the Papahanaumokuakea\nMarine National Monument between Nihoa and French Frigate Shoals,\nand hurricane conditions are expected there early Tuesday.\n \nRAINFALL: Lowell is expected to produce additional rainfall totals\nof 4 to 8 inches for Kauai, with maximum storm totals of 24 inches\npossible. For the Big Island, an additional 3 to 8 inches of rain is\nexpected with isolated storm totals of 12 inches possible. For Oahu\nand Maui county, an additional 2 to 5 inches of rain is expected\nwith isolated storm totals of 10 inches possible. This rainfall may\nproduce significant flash flooding and mudslides, especially across\nKauai county and portions of the Big Island.\n \nFor a complete depiction of forecast rainfall associated with\nLowell, please see the National Weather Service Storm Total Rainfall\nGraphic available at\nhttps://hurricanes.gov/storm_graphics/EP12/EP1226WPCQPF.gif\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...2-4 ft, with the highest expected values along the\nsouth coast of Kauai and the island of Niihau\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 \nTORNADOES: Several tornadoes are possible near Kauai and Niihau\nthrough the overnight period. A few tornadoes are also possible\nacross the remainder of the Hawaiian Islands.\n \nSURF: Swells from Lowell will continue to generate life-threatening\nsurf and rip current conditions during the next few days across many\nof the Hawaiian Islands.
