DISCUSSION AND OUTLOOK
———————-
At 11 p.m. HST (0900 UTC), the eye of Hurricane Lane was located by satellite and radar near latitude 16.3 North, longitude 156.9 West. Lane is moving toward the northwest near 7 mph (11 km/h). This general motion is expected through Thursday, with a gradual turn toward the northwest. On Friday, a turn toward the north is anticipated as Lane’s forward motion slows even more. A turn back toward the west is expected on Saturday. On the forecast track, the center of Lane will move very close to or over the main Hawaiian Islands tomorrow through Friday.

Maximum sustained winds remain near 145 mph (230 km/h) with higher gusts. Lane is a powerful category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some weakening is forecast during the next few days, but Lane is expected to remain a hurricane as it approaches the islands.

Hurricane-force winds extend outward up to 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km).

The estimated minimum central pressure is 939 mb (27.73 inches).

HAZARDS AFFECTING LAND
———————-
WIND: Tropical storm conditions are expected on portions of the Big Island beginning early Thursday morning, with hurricane conditions expected in some areas Thursday afternoon or Thursday night. Tropical storm conditions are expected to begin over portions of Maui county on Thursday, with hurricane conditions expected in some areas Thursday night into Friday. Tropical storm conditions are expected to begin on Oahu late Thursday night, with hurricane conditions expected Friday into Friday night.

RAINFALL: Rain bands from Hurricane Lane will continue to overspread the Hawaiian Islands tonight and Thursday. Excessive rainfall associated with Lane will impact the Hawaiian Islands into the weekend, leading to significant and life-threatening flash flooding and landslides. Lane is expected to produce total rain accumulations of 10 to 20 inches, with localized amounts in excess of 30 inches over the Hawaiian Islands.

SURF: As Lane is slow-moving, large swells generated by Lane will severely impact the Hawaiian Islands over the next couple of days. These swells will produce very large and damaging surf along exposed west and south facing shorelines. A prolonged period of high surf will likely lead to significant coastal erosion.

STORM SURGE: The combination of a dangerous storm surge and large breaking waves will raise water levels by as much as 2 to 4 feet above normal tide levels along south and west facing shores near the center of Lane. The surge will be accompanied by large and destructive waves.

KEY MESSAGES:

1. Lane will pass dangerously close to the main Hawaiian Islands as a hurricane Thursday and Friday, and is expected to bring damaging winds. These winds can be accelerated over and downslope from elevated terrain and will be higher in high rise buildings.

2. The slow movement of Lane also greatly increases the threat for prolonged heavy rainfall and extreme rainfall totals. This is expected to lead to life-threatening flash flooding and landslides over all the Hawaiian Islands.

3. Large and damaging surf can be expected along exposed shorelines, especially along south and west facing coasts, with localized storm surge exacerbating the impacts of a prolonged period of damaging surf.

4. Do not focus on the exact forecast track or intensity of Lane, and be prepared for adjustments to the forecast. Although the official forecast does not explicitly indicate Lane’s center making landfall over any of the islands, this could still occur. Even if the center of Lane remains offshore, severe impacts could still be realized as they extend well away from the center.

Public should prepare for Tropical Cyclone Lane

HONOLULU — HI-EMA recommends residents and visitors take the following actions to prepare for any possible hurricane or tropical cyclone:

  • Prepare an “emergency kit” of a minimum of 14 days of food, water, and other supplies.
  • Talk with family members and develop a clear understanding of what you will do if a hurricane or tropical storm threatens. Prepare an action plan that includes details such as whether your family plans to shelter in place or evacuate.
  • Know if your home is in an inundation zone, flood zone, or susceptible to high winds and other hazards. Know if your home is retrofitted with hurricane resistant clips or straps.
  • Stay tuned to local media and their websites/applications regarding weather updates.
  • Sign up for local notification systems (i.e., HNL.Info).
  • Get to know your neighbors and community so you can help each other.
  • Walk your property and check for potential flood threats. Clear your gutters and other drainage systems. Remove and secure loose items. Keep your car gas tanks filled.
  • Prepare your pets by checking or purchasing a carrier and other preparedness items. A pet carrier is necessary for your pet’s safety if you plan to evacuate to a pet-friendly shelter. Don’t forget 14 days of food and water for your furry family members.
  • Set aside an emergency supply of any needed medication and keep a copy of your prescriptions in case you run out of medication after a disaster.
  • Secure your important documents in protective containers.
  • Visitors should download GoHawaii App and read the Hawaii Tourism Authority’s Travel Safety Brochure at www.travelsmarthawaii.com.
