DISCUSSION AND OUTLOOK

At 1100 AM HST (2100 UTC), the center of Hurricane Lowell was
located near latitude 13.5 North, longitude 163.1 West. Lowell is
moving toward the west-northwest near 7 mph (11 km/h). A turn 
toward the northwest is expected by this evening, followed by a 
northward to north-northeastward motion with an increase in forward 
speed on Sunday and Monday.  On the forecast track, the center of 
Lowell will move across portions of the Papahanaumokuakea Marine 
National Monument, just to the west of the main Hawaiian Islands, 
Monday night.
 
Maximum sustained winds are near 145 mph (230 km/h) with higher
gusts.  Lowell is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Fluctuations in intensity are possible during
the next day or so, followed by a gradual weakening trend on Sunday
and Monday.
 
Hurricane-force winds extend outward up to 60 miles (95 km) from the
center and tropical-storm-force winds extend outward up to 160 miles
(260 km).
 
The estimated minimum central pressure is 936 mb (27.64 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: Tropical storm conditions are possible in Kauai County by 
late Monday or Monday night. Hurricane conditions are possible in 
eastern portions of the Papahanaumokuakea Marine National Monument 
Monday night, with tropical storm conditions beginning by late 
Monday.
 
RAINFALL: Hurricane Lowell is expected to produce rainfall totals of
3 to 6 inches, with maximum totals exceeding 10 inches possible, for
Kauai and the Big Island. For Maui, 2 to 4 inches of rain are
expected, with isolated maximum totals of 8 inches possible. Across
the remaining islands, rainfall of 1 to 2 inches with maximum
amounts of 4 inches is possible. This rainfall may produce locally
significant flash flooding and mudslides, especially in areas of
steep terrain.
 
For a complete depiction of forecast rainfall associated with
Hurricane Lowell, please see the National Weather Service Storm
Total Rainfall Graphic available at
hurricanes.gov/graphics_ep12.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...1-3 ft
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.
 
SURF: Swells from Lowell are likely to cause life-threatening surf
and rip current conditions during the next several days across
many of the Hawaiian islands. Please consult products from your
local weather office.
