DISCUSSION AND OUTLOOK
———————-
At 11 p.m. HST (0900 UTC), the center of Hurricane Lane was located near latitude 14.7 North, longitude 154.5 West. Lane is moving toward the west-northwest near 9 mph (15 km/h) and this motion is expected to continue tonight. A turn toward the northwest is expected on Wednesday, followed by a turn to the north-northwest on Thursday. On the forecast track, the center of Lane will move very close to or over the main Hawaiian Islands from Thursday through Saturday.

Maximum sustained winds are near 160 mph (260 km/h) with higher gusts. Lane is a category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Slow weakening is forecast during the next 48 hours, but Lane is forecast to remain a dangerous hurricane as it draws closer to the Hawaiian 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 930 mb (27.47 inches).

HAZARDS AFFECTING LAND
———————-
WIND: Tropical storm conditions are expected within the Hurricane Warning area beginning late Wednesday night into early Thursday morning, with hurricane conditions expected somewhere within the warning area on Thursday. Tropical storm conditions are possible within the Hurricane Watch area beginning Thursday into Thursday night, with hurricane conditions possible late Thursday night into Friday.

RAINFALL: Excessive rainfall associated with Lane is expected to affect portions of the Hawaiian Islands from late Wednesday into the weekend, leading to flash flooding and landslides. Lane is expected to produce total rain accumulations of 10 to 15 inches with isolated amounts greater than 20 inches over the Hawaiian Islands.

SURF: Large swells generated by Lane will impact the Hawaiian Islands, beginning tonight on the Big Island, spreading across the remainder of the island chain on Wednesday. These swells will produce large and potentially damaging surf along exposed west, south and east facing shorelines.

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.
