The center of Lane will track dangerously close to the Hawaiian Islands from Thursday through Saturday. Regardless of the exact track of the storm center, life threatening impacts are likely over some areas as this strong hurricane makes it's closest approach. Just a reminder that impacts from a hurricane extend far from the center of the storm and slight changes to the forecast track this close to the islands will produce rapid changes to the local forecast impacts. The onset of damaging tropical-storm-force winds on the Big Island could start later this evening, with dangerous hurricane force winds starting in the overnight hours. In Maui County, damaging winds could begin as early as Thursday afternoon, with dangerous hurricane force winds possible starting on Thursday night. On Oahu, damaging winds could begin as early as Thursday evening, with dangerous hurricane force winds possible by Friday morning. Hurricane Warnings may need to be expanded to include other islands as Lane draws closer. Bands of intense showers and thunderstorms surrounding Lane will begin to spread across the state from the southeast towards the northwest, reaching the Big Island later this morning. Excessive rainfall is possible which could lead to deadly flash flooding, landslides and mudslides. Flooding can occur even in areas not usually prone to flooding. Storm total rainfall amounts greater than 20 inches are possible. Swell generated by Lane will produce very large and rough surf, with dangerous rip currents along south, southeast and southwest facing shores. Tornadoes and large waterspouts will be possible associated with Lane, mainly along and to the right of the track of the hurricane. Potential impacts FLOODING RAIN: Protect against life-threatening rainfall flooding having possible devastating impacts across the Hawaiian islands. Potential impacts include: - Extreme rainfall flooding may prompt numerous evacuations and rescues. - Rivers and tributaries may overwhelmingly overflow their banks in many places with deep moving water. Small streams, creeks, canals, arroyos, and ditches may become raging rivers. In mountain areas, deadly runoff may rage down valleys while increasing susceptibility to rockslides and mudslides. Flood control systems and barriers may become stressed. - Flood waters can enter numerous structures within multiple communities, some structures becoming uninhabitable or washed away. Numerous places where flood waters may cover escape routes. Streets and parking lots become rivers of raging water with underpasses submerged. Driving conditions become very dangerous. Numerous road and bridge closures with some weakened or washed out. WIND: Protect against life-threatening wind having possible extensive impacts across Maui County, Oahu, and western and southern sections of the Big Island. Potential impacts in this area include: - Considerable roof damage to sturdy buildings, with some having window, door, and garage door failures leading to structural damage. Mobile homes severely damaged, with some destroyed. Damage accentuated by airborne projectiles. Locations may be uninhabitable for weeks. - Many large trees snapped or uprooted along with fences and roadway signs blown over. - Some roads impassable from large debris, and more within urban or heavily wooded places. Several bridges, causeways, and access routes impassable. - Large areas with power and communications outages. Also, protect against dangerous wind having possible significant impacts across the northern and eastern sections of the Big Island and Kauai. SURGE: Protect against life-threatening surge having possible significant impacts across south and west facing coasts. Potential impacts in this area include: - Areas of inundation with storm surge flooding accentuated by waves. Damage to several buildings, mainly near the coast. - Sections of near-shore escape routes and secondary roads become weakened or washed out, especially in usually vulnerable low spots. - Major beach erosion with heavy surf breaching dunes. Strong and numerous rip currents. - Moderate damage to marinas, docks, boardwalks, and piers. Several small craft broken away from moorings, especially in unprotected anchorages. Elsewhere across the Hawaiian islands, little to no impact is anticipated. TORNADOES: Protect against a tornado event having possible limited impacts across the Hawaiian islands. Potential impacts include: - The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events. - A few places may experience tornado damage, along with power and communications disruptions. - Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow-rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings. Precautionary/preparedness actions EVACUATIONS: Listen to local official for recommended preparedness actions, including possible evacuation. If ordered to evacuate, do so immediately. For those not under evacuation orders, assess the risk from wind, falling trees, and flooding at your location. If you decide to move, relocate to a safer location nearby. If you do not relocate, help keep roadways open for those under evacuation orders. If evacuating, leave with a destination in mind and allow extra time to get there. Take your emergency supplies kit. Gas up your vehicle ahead of time. Let others know where you are going prior to departure. Secure loose items and pets in the car, and avoid distracted driving. If evacuating, follow designated evacuation routes. Seek traffic information on roadway signs, the radio, and from official sources. OTHER PREPAREDNESS INFORMATION: Now is the time to complete all preparations to protect life and property in accordance with your emergency plan. Ensure you are in a safe location before the onset of strong winds or possible flooding. If you are relocating to safe shelter, leave as early as possible. Allow extra time to reach your destination. Many roads and bridges will be closed once strong winds arrive. Check the latest weather forecast before departing and drive with caution. Keep cell phones well charged. Cell phone chargers for automobiles can be helpful, but be aware of your risk for deadly carbon monoxide poisoning if your car is left idling in a garage or other poorly ventilated area. It is important to remain calm, informed, and focused during an emergency. Be patient and helpful with those you encounter. If you are a visitor, be sure to know the name of the city or town in which you are staying and the name of the county or parish in which it resides. Listen for these locations in local news updates. Pay attention for instructions from local authorities. Rapidly rising flood waters are deadly. If you are in a flood-prone area, consider moving to higher ground. Never drive through a flooded roadway. Remember, turn around don't drown! If in a place that is vulnerable to high wind, such as near large trees, a manufactured home, upper floors of a high-rise building, or on a boat, consider moving to a safer shelter before the onset of strong winds or flooding. Closely monitor weather.gov, NOAA Weather radio or local news outlets for official storm information. Be ready to adapt to possible changes to the forecast. Ensure you have multiple ways to receive weather warnings.
