As the center of Lowell passes southwest then\nwest of Niihau through tonight, expect damaging winds, heavy flooding\nrainfall, and extremely dangerous and damaging surf to develop over\nportions of the Hawaiian Islands into Tuesday morning. A Hurricane\nWarning remains in effect for Kauai and Niihau, and a Tropical Storm\nWarning is in effect for Oahu. Preparations should be rushed to\ncompletion in the warned areas. \n\nEast to southeast winds will gradually strengthen over the western\nhalf of the Hawaiian Islands through the afternoon. Several stations\non southern Kauai, including Lihue Airport, are already measuring\nsustained winds of 30 mph or more with gusts over 40 mph. Damaging\ntropical storm force winds could develop as early as late this\nafternoon across Kauai County and early this evening on Oahu.\nHurricane conditions are expected over portions of Kauai County\novernight, with the highest probability of hurricane force winds\noccurring on Niihau. It is important to note that winds can be\naccelerated over and downwind of terrain, leading to areas of\nhurricane force wind gusts. As winds shift from east to southeast this\nafternoon to south overnight, areas affected by downslope wind gusts\nwill likely change.\n\nA broad shield of deep tropical moisture surrounding Lowell will\ncontinue to spread over all Hawaiian islands through tonight,\nincreasing the threat of heavy rain and isolated thunderstorms. Heavy\ndownpours could lead to flash flooding and/or mudslides, especially in\nsteep terrain, and flash flooding has already been reported on\nportions of Kauai. Rainbands could become persistent and anchored in\nsome areas, exacerbating the flash flood threat. The risk of flash\nflooding and mudslides is greatest for Kauai and Niihau, but also\nexists for all other islands due to the extent of the moisture\nassociated with Lowell. Over 15 inches of rain is possible over\nportions of Kauai, mainly over the interior mountains. A foot or more\nremains possible over southeast Big Island.\n\nAn extremely large south to southwest swell generated by Lowell will\nrapidly build through the remainder of the day and peak tonight over\nportions of Hawaiian waters. A High Surf Warning is in effect for\nsouth-facing shores of all islands and for west-facing shores of the\nBig Island. Dangerously large and damaging surf and coastal inundation\nare expected along the immediate coast of exposed south- and\nwest-facing shores, particularly on Kauai and Niihau, and possibly\nOahu. The highest surf may reach 20 to 30 feet on Kauai and Niihau\ntonight, then rapidly diminish on Tuesday. Extra large surf, on top of\n1 to 4 feet of storm surge and peak afternoon high tides, will\ngenerate major wave run-up and coastal inundation along exposed low\nlying areas of south- and west-facing shores, particularly for Kauai\nand Niihau, and possibly for Oahu. \n\nConditions will be conducive for fast-moving, short-lived waterspouts\nand tornadoes in the rainbands associated with Lowell, especially near\nKauai and Niihau. This threat will continue through tonight, then\ndiminish quickly Tuesday morning.\n\n\nPOTENTIAL IMPACTS\n-----------------\n\n* WIND:\nProtect against life-threatening wind having possible extensive \nimpacts across Niihau and Kauai. Potential impacts in this area \ninclude:\n    - Considerable roof damage to sturdy buildings, with some having \n      window, door, and garage door failures leading to structural \n      damage. Mobile homes severely damaged, with some destroyed. \n      Damage accentuated by airborne projectiles. Locations may be \n      uninhabitable for weeks.\n    - Many large trees snapped or uprooted along with fences and \n      roadway signs blown over.\n    - Some roads impassable from large debris, and more within urban \n      or heavily wooded places. Several bridges, causeways, and \n      access routes impassable.\n    - Large areas with power and communications outages.\n\nAlso, protect against dangerous wind having possible limited to \nsignificant impacts across Oahu.\n\n* FLOODING RAIN:\nProtect against life-threatening rainfall flooding having possible \nextensive impacts across Niihau and Kauai. Potential impacts include:\n    - Major rainfall flooding may prompt many evacuations and rescues.\n    - Rivers and tributaries may rapidly overflow their banks in \n      multiple places. Small streams, creeks, canals, arroyos, and \n      ditches may become dangerous rivers. In mountain areas, \n      destructive runoff may run quickly down valleys while \n      increasing susceptibility to rockslides and mudslides. Flood \n      control systems and barriers may become stressed.\n    - Flood waters can enter many structures within multiple \n      communities, some structures becoming uninhabitable or washed \n      away. Many places where flood waters may cover escape routes. \n      Streets and parking lots become rivers of moving water with \n      underpasses submerged. Driving conditions become dangerous. \n      Many road and bridge closures with some weakened or washed out.\n\nProtect against dangerous rainfall flooding having possible \nsignificant impacts across all other islands.\n\n* SURGE:\nProtect against life-threatening surge having possible significant \nimpacts across Niihau and Kauai. Potential impacts in this area \ninclude:\n    - Areas of inundation with storm surge flooding accentuated by \n      waves. Damage to several buildings, mainly near the coast.\n    - Sections of near-shore escape routes and secondary roads become \n      weakened or washed out, especially in usually vulnerable low \n      spots.\n    - Major beach erosion with heavy surf overtopping nearby roadways.\n    - Moderate damage to marinas, docks, and piers. Several small \n      craft broken away from moorings, especially in unprotected \n      anchorages.\n\nElsewhere across the Hawaiian islands, little to no impact is \nanticipated.\n\n* TORNADOES:\nPrepare for a dangerous tornado event having possible significant \nimpacts across Niihau and Kauai. Potential impacts include:\n    - The occurrence of scattered tornadoes can hinder the execution \n      of emergency plans during tropical events.\n    - Several places may experience tornado damage with a few spots \n      of considerable damage, power loss, and communications failures.\n    - Locations could realize roofs torn off frame houses, mobile \n      homes demolished, boxcars overturned, large trees snapped or \n      uprooted, vehicles tumbled, and small boats tossed about. \n      Dangerous projectiles can add to the toll.\n\nPrepare for a tornado event having possible limited impacts across \nthe rest of the main Hawaiian Islands from Oahu to the Big Island.\n\nPRECAUTIONARY/PREPAREDNESS ACTIONS\n----------------------------------\n\n* EVACUATIONS:\nFollow the advice of local officials.\n\n* OTHER PREPAREDNESS INFORMATION:\nNow is the time to complete all preparations to protect life and \nproperty in accordance with your emergency plan. Ensure you are in a \nsafe location before the onset of strong winds or possible flooding.\n\nIf you are relocating to safe shelter, leave as early as possible. \nAllow extra time to reach your destination. Many roads and bridges \nwill be closed once strong winds arrive. Check the latest weather \nforecast before departing and drive with caution.\n\nIf heading to a community shelter, become familiar with the shelter \nrules before arrival, especially if you have special needs or have \npets. Take essential items with you from your Emergency Supplies Kit.\n\nFailure to adequately shelter may result in serious injury or loss of \nlife. Always heed the advice of local officials and comply with any \norders that are issued. Remember, during the storm 9 1 1 Emergency \nServices may not be able to immediately respond if conditions are \nunsafe. This should be a big factor in your decision making.\n\nKeep cell phones well charged. Cell phone chargers for automobiles \ncan be helpful, but be aware of your risk for deadly carbon monoxide \npoisoning if your car is left idling in a garage or other poorly \nventilated area.\n\nIt is important to remain calm, informed, and focused during an \nemergency. Be patient and helpful with those you encounter.\n\nIf you are a visitor, be sure to know the name of the city or town in \nwhich you are staying and the name of the county or parish in which \nit resides. Listen for these locations in local news updates. Pay \nattention for instructions from local authorities.\n\nStorm surge is the leading killer associated with tropical storms and \nhurricanes! Make sure you are in a safe area away from the surge \nzone. Even if you are not in a surge-prone area, you could find \nyourself cutoff by flood waters during and after the storm. Heed \nevacuation orders issued by the local authorities.\n\nRapidly rising flood waters are deadly. If you are in a flood-prone \narea, consider moving to higher ground. Never drive through a flooded \nroadway. Remember, turn around don't drown!\n\nIf a Tornado Warning is issued for your area, be ready to shelter \nquickly, preferably away from windows and in an interior room not \nprone to flooding. If driving, scan the roadside for quick shelter \noptions.\n\nIf in a place that is vulnerable to high wind, such as near large \ntrees, a manufactured home, upper floors of a high-rise building, or \non a boat, consider moving to a safer shelter before the onset of \nstrong winds or flooding.\n\nClosely monitor weather.gov, NOAA Weather radio or local news outlets \nfor official storm information. Be ready to adapt to possible changes \nto the forecast. Ensure you have multiple ways to receive weather \nwarnings.\n\n* ADDITIONAL SOURCES OF INFORMATION:\n- For information on appropriate preparations see ready.gov\n- For information on creating an emergency plan see getagameplan.org\n- For additional disaster preparedness information see redcross.org\n\nNEXT UPDATE\n-----------\n\nThe next local statement will be issued by the National Weather \nService in Honolulu HI around 500 PM HST, or sooner if conditions \nwarrant.\n\n"}
