Hurricane Lane weakens slightly

At 200am HST (1200 UTC), the eye of Hurricane Lane was located by satellite and radar near latitude 16.5 N, longitude 157.3 W, and moving toward the northwest near 7mph (11 km/h).

This general motion is expected to continue today, with a gradual turn toward the north-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 later today through Friday.

Maximum sustained winds are near 130 mph (215 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 day or so, with more significant weakening thereafter. Lane is expected to remain a hurricane as it approaches the islands.

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

Tropical storm conditions are expected on portions of the Big Island beginning later this morning, with hurricane conditions expected in some areas by tonight. Tropical storm conditions are expected to begin over portions of Maui county later today, with hurricane conditions expected in some areas by Friday. Tropical storm conditions are expected to begin on Oahu late tonight, with hurricane conditions expected Friday into Friday night.

Rain bands from Hurricane Lane will continue to overspread the Hawaiian Islands. 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 10-20 inches, with localized amounts in excess of 30 inches over the Hawaiian Islands.

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.

The combination of a dangerous storm surge and large breaking waves will raise water levels by as much as 2-4 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.
