DISCUSSION AND OUTLOOK
----------------------
At 800 AM HST (1800 UTC), the eye of Hurricane Lane was located by
U.S. Air Force Reserve Hurricane Hunter aircraft near latitude 14.1
North, longitude 152.6 West. Lane is moving toward the west near 
9 mph (14 km/h) and this general motion is expected to continue
through tonight, with a slight decrease in forward speed. A turn
toward the northwest is expected Wednesday into Thursday. On the
forecast track, the center of Lane will pass close to Hawaii and
Maui Counties on Thursday and Thursday night.
 
Maximum sustained winds have increased to near 155 mph (250
km/h) with higher gusts.  Lane remains a powerful Category 4
hurricane on the Saffir-Simpson Hurricane Wind Scale. Slight
weakening is expected during the next couple of days, 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 minimum central pressure as recently measured by the hurricane
hunter aircraft is 940 mb (27.76 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND: Hurricane conditions are possible within the Hurricane Watch
area on Thursday.
 
RAINFALL: Excessive rainfall associated with Lane is expected
to affect portions of the Hawaiian Islands from 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
maximum amounts of 20 inches over the Hawaiian Islands.
 
SURF: Large swells generated by Lane will impact the Hawaiian
Islands this week. These swells will produce large and potentially
damaging surf along exposed south and west facing shorelines.
