DISCUSSION AND OUTLOOK
----------------------
At 1100 AM HST (2100 UTC), the eye of Hurricane Lane was located
near latitude 15.5 North, longitude 155.9 West. Lane is moving
toward the west-northwest near 8 mph (13 km/h). A gradual turn
toward the northwest is expected today followed by a more northward
motion on Thursday. 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 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. A steady weakening trend is forecast to begin
today, but Lane is expected to remain a dangerous 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
(220 km).
 
The estimated minimum central pressure is 935 mb (27.61 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected within the Hurricane
Warning area beginning late tonight 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: Rainbands from Hurricane Lane are moving ashore on
the Puna and Kau districts. Excessive rainfall associated with Lane
is expected to affect portions of the Hawaiian Islands from late
today into the weekend. This could lead to major flash flooding and
landslides. Lane is expected to produce total rain accumulations of
10 to 15 inches with localized amounts in excess of 20 inches over
the Hawaiian Islands.
 
SURF: Large swells generated by Lane will impact the Hawaiian
Islands, spreading across the island chain today and tonight. 
These swells will produce very large and potentially damaging surf
along exposed west, south and east facing shorelines.
