SITUATION OVERVIEW
------------------

At 11 am HST, the eye of major Hurricane Lowell was located about
550 miles south-southwest of Kauai. Lowell has maximum sustained winds
of 120 mph, and is now moving toward the north at 6 mph. Lowell is 
expected to turn more toward the north- northeast tonight through 
Tuesday while accelerating. Some fluctuations in intensity are expected
in the short term, with gradual weakening expected tonight into 
Monday. The eye of Lowell is currently forecast to make it's closest 
approach to the main Hawaiian Islands Monday night, passing 90 to 150 
miles west of Niihau. Lowell is expected to remain a hurricane while
passing near Hawaii.

Strong, gusty winds on the eastern side of Lowell's circulation are
expected to affect Kauai and Niihau as Hurricane Lowell passes. Winds
will increase on Monday as the hurricane approaches the western end of
the chain. Based on the current forecast, tropical storm force winds,
sustained 39 mph or higher, are expected Monday afternoon. Plan to 
have your preparations for damaging winds complete by midday, with 
winds peaking Monday night. Even higher gusts, 60 mph or more, are 
possible over Kauai and Niihau where winds are accelerated by terrain.

Starting later today, a very large shield of deep tropical moisture
surrounding Lowell will spread northward over the main Hawaiian
islands from south to north, bringing increasing showers. Squally
downpours could lead to flash flooding, along with mudslides in steep
terrain. Rainbands could become persistent and anchored in some areas,
which would exacerbate the flash flood threat. The risk of flash
flooding and mudslides is greatest for Kauai and Niihau, but also
exists for other islands as well due to the extent of the moisture
associated with Lowell. Over a foot of rain is possible over portions
of Kauai, mainly over the interior mountains.

Surf is expected to increase quickly on south and west facing shores
tonight, reaching warning levels by Monday. Damaging surf and some
coastal inundation are expected along the immediate coast on exposed
south and west facing shores on Kauai and Niihau Monday and Monday
night, before diminishing on Tuesday. Highest surf heights in those
areas may reach 20 to 30 feet, along with 1 to 3 feet of coastal
inundation. 

Conditions will become favorable for fast-moving, short-lived
waterspouts and tornadoes in the rainbands associated with Lowell,
mainly near Kauai and Niihau, Monday afternoon. This threat will
continue into Monday night, then diminish quickly Tuesday morning.



POTENTIAL IMPACTS
-----------------

* WIND:
Protect against dangerous wind having possible significant impacts
across Kauai and Niihau. Potential impacts in this area include:
    - Some damage to roofing and siding materials, along with damage 
      to porches, awnings, carports, and sheds. A few buildings 
      experiencing window, door, and garage door failures. Mobile 
      homes damaged, especially if unanchored. Unsecured lightweight 
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater 
      numbers in places where trees are shallow rooted. Several 
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban 
      or heavily wooded places. A few bridges, causeways, and access 
      routes impassable.
    - Scattered power and communications outages, but more prevalent 
      in areas with above ground lines.

Elsewhere across the Hawaiian islands, little to no impact is 
anticipated.

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across Kauai and Niihau. Potential impacts include:
    - Major rainfall flooding may prompt many evacuations and rescues.
    - Rivers and tributaries may rapidly overflow their banks in 
      multiple places. Small streams, creeks, canals, arroyos, and 
      ditches may become dangerous rivers. In mountain areas, 
      destructive runoff may run quickly down valleys while 
      increasing susceptibility to rockslides and mudslides. Flood 
      control systems and barriers may become stressed.
    - Flood waters can enter many structures within multiple 
      communities, some structures becoming uninhabitable or washed 
      away. Many places where flood waters may cover escape routes. 
      Streets and parking lots become rivers of moving water with 
      underpasses submerged. Driving conditions become dangerous. 
      Many road and bridge closures with some weakened or washed out.

Protect against dangerous rainfall flooding having possible significant
impacts across the rest of the main Hawaiian Islands from Oahu to the 
Big Island.

* SURGE:
Protect against locally hazardous surge having possible limited impacts
across Kauai and Niihau. Potential impacts in this area include:
    - Localized inundation with storm surge flooding mainly along 
      immediate shorelines and in low-lying spots, or in areas 
      farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots become overspread 
      with surge water. Driving conditions dangerous in places where 
      surge water covers the road.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly 
      in usually vulnerable locations. Strong rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks, 
      and piers. A few small craft broken away from moorings.

Elsewhere across the Hawaiian islands, little to no impact is 
anticipated.

* TORNADOES:
Protect against a dangerous tornado event having possible significant
impacts across Niihau and Kauai. Potential impacts include:
    - The occurrence of scattered tornadoes can hinder the execution 
      of emergency plans during tropical events.
    - Several places may experience tornado damage with a few spots 
      of considerable damage, power loss, and communications failures.
    - Locations could realize roofs torn off frame houses, mobile 
      homes demolished, boxcars overturned, large trees snapped or 
      uprooted, vehicles tumbled, and small boats tossed about. 
      Dangerous projectiles can add to the toll.

Protect against a tornado event having possible limited impacts 
across the rest of the main Hawaiian Islands from Oahu to the Big
Island.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
Follow the advice of local officials

* OTHER PREPAREDNESS INFORMATION:
Now is the time to complete all preparations to protect life and 
property in accordance with your emergency plan. Ensure you are in a 
safe location before the onset of strong winds or possible flooding.

If you are relocating to safe shelter, leave as early as possible. 
Allow extra time to reach your destination. Many roads and bridges 
will be closed once strong winds arrive. Check the latest weather 
forecast before departing and drive with caution.

If heading to a community shelter, become familiar with the shelter 
rules before arrival, especially if you have special needs or have 
pets. Take essential items with you from your Emergency Supplies Kit.

Failure to adequately shelter may result in serious injury or loss of 
life. Always heed the advice of local officials and comply with any 
orders that are issued. Remember, during the storm 9 1 1 Emergency 
Services may not be able to immediately respond if conditions are 
unsafe. This should be a big factor in your decision making.

Keep cell phones well charged. Cell phone chargers for automobiles 
can be helpful, but be aware of your risk for deadly carbon monoxide 
poisoning if your car is left idling in a garage or other poorly 
ventilated area.

It is important to remain calm, informed, and focused during an 
emergency. Be patient and helpful with those you encounter.

If you are a visitor, be sure to know the name of the city or town in 
which you are staying and the name of the county or parish in which 
it resides. Listen for these locations in local news updates. Pay 
attention for instructions from local authorities.

Storm surge is the leading killer associated with tropical storms and 
hurricanes! Make sure you are in a safe area away from the surge 
zone. Even if you are not in a surge-prone area, you could find 
yourself cutoff by flood waters during and after the storm. Heed 
evacuation orders issued by the local authorities.

Rapidly rising flood waters are deadly. If you are in a flood-prone 
area, consider moving to higher ground. Never drive through a flooded 
roadway. Remember, turn around don't drown!

If a Tornado Warning is issued for your area, be ready to shelter 
quickly, preferably away from windows and in an interior room not 
prone to flooding. If driving, scan the roadside for quick shelter 
options.

If in a place that is vulnerable to high wind, such as near large 
trees, a manufactured home, upper floors of a high-rise building, or 
on a boat, consider moving to a safer shelter before the onset of 
strong winds or flooding.

Closely monitor weather.gov, NOAA Weather radio or local news outlets 
for official storm information. Be ready to adapt to possible changes 
to the forecast. Ensure you have multiple ways to receive weather 
warnings.
