DISCUSSION AND OUTLOOK
At 1100 PM 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
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
