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

As Hurricane Douglas quickly moves through the area over the next
24 hours from east to west, expect damaging winds, heavy rainfall,
coastal flooding, and life-threatening surf. Douglas is now passing
dangerously close to Maui and is expected to move near or directly
over portions of Oahu this afternoon into tonight, then Kauai County
tonight into Monday. Regardless of the exact track, interests are
reminded that impacts can occur well away from the tropical cyclone
center. It is also important to note that the mountainous terrain of
the islands can cause strong localized accelerations of the wind
through gaps and where winds blow downslope.

Total rainfall accumulations of 5 to 10 inches, with locally higher
amounts to 15 inches, will be possible as Douglas moves through. While
the highest rainfall will favor windward and northern facing slopes,
leeward and southern facing slopes could also experience flooding.

Significant coastal impacts are expected due to life-threatening surf
along exposed shores. A combination of higher than predicted water
levels, storm surge, and surf will lead to significant beach erosion,
with water potentially overwashing onto vulnerable low- lying coastal
roadways, especially at and around the daily high tides.

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

* WIND:
Protect against life-threatening wind having possible extensive
impacts across State of Hawaii. Potential impacts in
this area include:
    - Considerable roof damage to sturdy buildings, with some having
      window, door, and garage door failures leading to structural
      damage. Mobile homes severely damaged, with some destroyed.
      Damage accentuated by airborne projectiles. Locations may be
      uninhabitable for weeks.
    - Many large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. Several bridges, causeways, and
      access routes impassable.
    - Large areas with power and communications outages.


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

* SURGE:
Protect against locally hazardous surge having possible limited
impacts across State of Hawaii. 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.

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across State of Hawaii. 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.


* TORNADOES:
Little to no impacts are anticipated at this time
across the Hawaiian islands.

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

* EVACUATIONS:
WATCH/WARNING PHASE - Listen to local official for recommended
preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.

WATCH/WARNING PHASE - For those not under evacuation orders, assess
the risk from wind, falling trees, and flooding at your location. If
you decide to move, relocate to a safer location nearby. If you do
not relocate, help keep roadways open for those under evacuation
orders.

WATCH/WARNING PHASE - If evacuating, leave with a destination in mind
and allow extra time to get there. Take your emergency supplies kit.
Gas up your vehicle ahead of time.

WATCH/WARNING PHASE - Let others know where you are going prior to
departure. Secure loose items and pets in the car, and avoid
distracted driving.

WATCH/WARNING PHASE - If evacuating, follow designated evacuation
routes. Seek traffic information on roadway signs, the radio, and
from official sources.

IMMINENT/ONGOING PHASE - Do not enter evacuated areas until officials
have given the all clear to return.

RECOVERY PHASE - Do not enter evacuated areas until officials have
given the all clear to return.


* 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.
