8 AM, Friday Aug. 24, 2018: NWS Central Pacific Hurricane Center, Honolulu: HURRICANE LANE LURKING JUST SOUTH OF THE ISLANDS BRINGING STRONG WINDS AND SIGNIFICANT FLOODING TO SOME AREAS

At 8 a.m., the center of Hurricane Lane was estimated by radar and satellite to be near latitude 18.8 north, longitude 158.0 west., 140 miles WSW of Kailua-Kona and 170 miles S of Honolulu.

Lane is moving toward the north near 2 mph, and this general motion is expected to continue through
tonight.

A turn toward the west is anticipated on Saturday, with an increase in forward speed.

On the latest forecast track, the center of Lane will move dangerously close to portions of the central Hawaiian islands later today and tonight.

Maximum sustained winds are near 105 mph with higher gusts. Some additional weakening is forecast later today and tonight, but Lane is expected to remain a dangerous hurricane as it approaches the islands.

Further weakening is expected on Saturday.

Hurricane-force winds extend outward up to 35 miles from the center and tropical-storm-force winds extend outward up to 140 miles.

A weather station near Waimea on the Big Island recently reported sustained winds of 45 mph with gusts to 51 mph.

HAZARDS AFFECTING LAND

WIND: Tropical storm conditions are already occurring on the Big Island, Maui County and Oahu. These conditions will likely persist today. Hurricane conditions are expected over some areas of Maui County and Oahu starting tonight. Tropical storm or hurricane conditions are possible on Kauai starting tonight or Saturday.

RAINFALL: Rain bands will continue to overspread the Hawaiian Islands well ahead of Lane. Excessive rainfall associated with this slow moving hurricane will continue to impact the Hawaiian Islands into the weekend, leading to catastrophic and life-threatening flash flooding and landslides. Lane is expected to produce total rain accumulations of 10 to 20 inches, with localized amounts up to 40 inches possible over portions of the Hawaiian Islands. Over 30 inches of rain has already fallen at a couple locations on the windward side of the Big Island.

SURF: Very large swells generated by the slow moving hurricane will severely impact the Hawaiian Islands into this weekend. These swells will produce life-threatening and damaging surf along exposed shorelines, particularly today through Saturday. In addition, a prolonged period of extreme surf will also 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.
