DISCUSSION AND OUTLOOK
----------------------
At 1100 PM HST (0900 UTC), the center of Hurricane Lowell was
located near latitude 21.9 North, longitude 160.8 West. Lowell is
moving toward the north-northeast near 18 mph (30 km/h). A motion
toward the north-northeast and north at a similar forward speed is
forecast through Tuesday. The core of Lowell is expected to pass
near or just west of Niihau overnight into early Tuesday. Then,
Lowell is forecast to turn toward the northwest and west and slow
down on Wednesday and Thursday after passing the Hawaiian Islands.

Maximum sustained winds are near 110 mph (175 km/h) with higher
gusts. Lowell will remain a powerful hurricane while passing near
the Hawaiian Islands overnight into early Tuesday, and then
weakening is expected over the next several 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). Barking Sands (PHBK) on western Kauai recently
reported sustained winds of 51 mph (82 km/h) with a gust to 84 mph
(135 km/h). Lihue Airport (PHLI) along the southeastern coast of
Kauai recently reported sustained winds of 53 mph (85 km/h) with a
gust to 79 mph (127 km/h). Daniel K Inouye International Airport
(PHNL) in Honolulu recently reported a gust of 45 mph (72 km/h).

The estimated minimum central pressure based on aircraft data is
963 mb (28.44 inches).


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 spreading 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.

Tropical storm conditions are ongoing in the Papahanaumokuakea
Marine National Monument between Nihoa and French Frigate Shoals,
and hurricane conditions are expected there early Tuesday.

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://hurricanes.gov/storm_graphics/EP12/EP1226WPCQPF.gif

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.
