Lowell is moving \ntoward the west-northwest near 5 mph (7 km/h). A turn toward the \nnorth is expected on Sunday, followed by a north-northeastward \nmotion with an increase in forward speed Sunday night and Monday. On \nthe forecast track, the center of Lowell will move across portions \nof the Papahanaumokuakea Marine National Monument, just west of the \nmain Hawaiian Islands, Monday night.\n \nMaximum sustained winds are near 130 mph (215 km/h) with higher\ngusts. Lowell is a category 4 hurricane on the Saffir-Simpson\nHurricane Wind Scale. Some fluctuations in intensity remain possible \nthrough early Sunday, followed by gradual weakening Sunday and \nMonday.\n \nHurricane-force winds extend outward up to 45 miles (75 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 942 mb (27.82 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 possible in Kauai County by\nlate Monday or Monday night. Hurricane conditions are possible in\neastern portions of the Papahanaumokuakea Marine National Monument\nMonday night, with tropical storm conditions possibly beginning by\nlate Monday.\n\nRAINFALL: Hurricane Lowell is expected to produce rainfall totals of \n4 to 8 inches for Kauai, with maximum totals exceeding 12 inches \npossible. For the Big Island, 2 to 6 inches of rain is expected with \nisolated totals of 10 inches possible. For Maui, 2 to 4 inches of \nrain is expected, with isolated maximum totals of 8 inches possible. \nAcross the remaining islands, rainfall of 2 to 4 inches is possible. \nThis rainfall may produce significant flash flooding and mudslides, \nespecially on Kauai 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.
