DISCUSSION AND OUTLOOK
----------------------
At 500 AM HST (1500 UTC), the center of Hurricane Lowell was located
near latitude 23.7 North, longitude 160.7 West. Lowell is moving
toward the north near 18 mph (30 km/h).  This general motion is 
forecast through today, taking the core of Lowell farther from 
Kauai County. Lowell is then forecast to turn toward the northwest 
and west and slow down on Wednesday and Thursday after passing the 
main Hawaiian Islands.

Maximum sustained winds have decreased to near 90 mph (150 km/h) 
with higher gusts.  Weakening is forecast, and Lowell should become 
a tropical storm later today and continue to weaken for the next 
couple of days.
 
Hurricane-force winds extend outward up to 70 miles (110 km) from 
the center and tropical-storm-force winds extend outward up to 230 
miles (370 km).  Lihue Airport (PHLI) along the southeastern coast 
of Kauai recently reported sustained winds of 35 mph (56 km/h) with 
a gust to 47 mph (76 km/h). 

The estimated minimum central pressure is 967 mb (28.56 inches).

WIND: Hurricane conditions are occuring across portions of Kauai
County. Wind speeds atop and on the windward and leeward sides of
hills and mountains are often up to 30 percent stronger than the
near-surface winds. Tropical storm conditions, especially in gusts,
are occurring on Oahu.
 
Hurricane conditions are ongoing in the Papahanaumokuakea
Marine National Monument between Nihoa and French Frigate Shoals.
 
RAINFALL: Hurricane Lowell is expected to produce additional 
rainfall totals of 2 to 4 inches for Kauai, with maximum storm 
totals of 24 inches possible. For the Big Island, an additional 3 to 
6 inches of rain is expected with isolated storm totals of 8 inches 
possible. For Oahu and Maui counties, an additional 1 to 3 inches of 
rain is expected with isolated storm totals of 8 inches possible. 
This rainfall may produce significant flash flooding and mudslides, 
especially across Kauai county and portions of the Big Island.

STORM SURGE:  Water levels may remain elevated along the coasts of 
Niihau, Kauai, and Oahu due to large waves, and will begin to 
subside after the next high tide cycle.
 
SURF: Swells from Lowell will continue to generate life-threatening
surf and rip current conditions during the next few days across many
of the Hawaiian Islands. Please consult products from your local
weather office.
