A Hurricane Watch means that hurricane conditions are possible

the anticipated first occurrence of tropical-storm-force winds,
conditions that make outside preparations difficult or dangerous.

Northwestern Hawaiian Islands, should continue to closely monitor
the progress of Hurricane Lane. Additional Tropical Storm or
Hurricane Watches will likely be issued later today or tonight.
 
For storm information specific to your area, please monitor

DISCUSSION AND OUTLOOK
----------------------
At 500 AM HST (1500 UTC), the eye of Hurricane Lane was located
by satellite near latitude 14.1 North, longitude 152.3 West. Lane is
moving toward the west near 12 mph (19 km/h) and this 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.
 
Maximum sustained winds are near 150 mph (240 km/h) with higher
gusts.  Lane is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Slight weakening is expected 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 estimated minimum central pressure is 950 mb (28.06 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.
