Lowell is moving\ntoward the north-northeast near 14 mph (22 km/h). A north-\nnortheastward to northward motion at a faster forward speed is\nforecast through Tuesday. On the forecast track, the core of\nLowell is expected to near or just west of Niihau tonight and early\nTuesday. Lowell is then forecast to turn toward the northwest and\nslow down by early Wednesday after passing the Hawaiian Islands.\n \nMaximum sustained winds remain near 115 mph (185 km/h) with higher\ngusts.  Lowell is a category 3 hurricane on the Saffir-Simpson\nHurricane Wind Scale.  Gradual weakening is expected through\nTuesday. However, Lowell is forecast to remain a hurricane as it\npasses near the Hawaiian Islands.\n \nHurricane-force winds extend outward up to 60 miles (95 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 950 mb (28.06 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 expected in Kauai County beginning\nthis afternoon or evening. Wind speeds atop and on the windward and\nleeward sides of hills and mountains are often up to 30 percent\nstronger than the near-surface winds.  Tropical storm conditions\nare possible on Oahu beginning this afternoon.\n \nHurricane conditions are expected in the Papahanaumokuakea Marine\nNational Monument between Nihoa and French Frigate Shoals tonight,\nwith tropical storm conditions beginning this afternoon.\n \nRAINFALL:  Hurricane Lowell is expected to produce additional\nrainfall totals of 6 to 10 inches for Kauai, with maximum totals of\n16 inches possible. For the Big Island, 4 to 8 inches of rain is\nexpected with isolated totals of 12 inches possible. For Oahu and\nMaui county, 4 to 8 inches of rain is expected with isolated totals\nof 10 inches possible. This rainfall may produce significant flash\nflooding and mudslides, especially across Kauai county and portions\nof 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\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\nthis afternoon through tonight. A few tornadoes are also possible\nacross the remainder of the Hawaiian Islands.\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.
