DISCUSSION AND OUTLOOK
----------------------
At 200 AM HST (1200 UTC), the center of Hurricane Lowell was located 
by an Air Force Reserve Hurricane Hunter aircraft near latitude 22.9 
North, longitude 160.8 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 105 mph (165 km/h) 
with higher gusts.  Further weakening is expected during the next 
few days.  
 
Hurricane-force winds extend outward up to 70 miles (110 km) from
the center and tropical-storm-force winds extend outward up to 195
miles (315 km). Lihue Airport (PHLI) along the southeastern coast of
Kauai recently reported sustained winds of 53 mph (85 km/h) with a
gust to 75 mph (121 km/h). Daniel K Inouye International Airport
(PHNL) in Honolulu recently reported a gust of 43 mph (69 km/h).
 
The estimated minimum central pressure is 965 mb (28.50 inches) 
based on Air Force Reserve Hurricane Hunter dropsonde data.
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Lowell can be found in the Tropical Cyclone
Discussion under AWIPS header HFOTCDCP4 and WMO header WTPA44
PHFO.
 
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: Lowell is expected to produce additional rainfall totals
of 4 to 8 inches for Kauai, with maximum storm totals of 24 inches
possible. For the Big Island, an additional 3 to 8 inches of rain is
expected with isolated storm totals of 12 inches possible. For Oahu
and Maui County, an additional 2 to 5 inches of rain is expected
with isolated storm totals of 10 inches possible. This rainfall may
produce significant flash flooding and mudslides, especially across
Kauai County and portions of the Big Island.
 
For a complete depiction of forecast rainfall associated with
Lowell, please see the National Weather Service Storm Total Rainfall
Graphic available at
https://www.nhc.noaa.gov/graphics_cp4.shtml?rainqpf
 
STORM SURGE: The combination of storm surge and tide will cause
normally dry areas near the coast to be flooded by rising waters
moving inland from the shoreline. The water could reach the
following heights above ground somewhere in the indicated areas if
the peak surge occurs at the time of high tide...
 
Kauai County...2-4 ft, with the highest expected values along the
south coast of Kauai and the island of Niihau
Oahu...Up to 1 ft
 
The deepest water will occur along the immediate coast near and to
the right of the center, where the surge will be accompanied by
large and destructive waves. Surge-related flooding depends on the
relative timing of the surge and the tidal cycle, and can vary
greatly over short distances.
 
For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_cp4.shtml?peakSurge.
 
TORNADOES: Several tornadoes are possible near Kauai and Niihau
through the overnight period. A few tornadoes are also possible
across the remainder of the Hawaiian Islands.
 
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.
