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 possibly beginning by
late Monday.
 
RAINFALL: Hurricane Lowell is expected to produce rainfall totals of
4 to 8 inches for Kauai, with maximum totals exceeding 12 inches
possible. For the Big Island, 2 to 6 inches of rain is expected with
isolated totals of 10 inches possible. For Maui, 2 to 4 inches of
rain is expected, with isolated maximum totals of 8 inches possible.
Across the remaining islands, rainfall of 2 to 4 inches is possible.
This rainfall may produce significant flash flooding and mudslides,

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.
