DISCUSSION AND OUTLOOK
----------------------
At 500 PM HST (0300 UTC), the center of Hurricane Lane was located
near latitude 14.5 North, longitude 154.0 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 155 mph (250 km/h) with higher
gusts.  Lane is a category 4 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 929 mb (27.44 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.
