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

Major Hurricane Lane is passing to the south-southeast of the Big
Island tonight and is expected to begin a turn northwest toward the
islands later today. The center of Lane will track dangerously close
to the islands Thursday through Saturday. Regardless of the
exact track of the center, life threatening impacts are likely in some
areas as the hurricane makes it's closest approach. It is important to
remember that impacts from a hurricane extend far from the center of the
storm.

The onset of damaging tropical-storm-force winds on the Big Island
could start as early as this afternoon or evening, with dangerous
hurricane force winds possible by tonight. In Maui County,
damaging tropical-storm-force winds could begin as early Thursday,
with dangerous hurricane force winds possible starting on Thursday night.
On Oahu, damaging tropical-storm-force winds could begin as early as
Thursday, with dangerous hurricane force winds possible by Thursday night
into Friday. Hurricane Watches and Warnings may need to be expanded to
include other islands as Lane draws closer.

Bands of intense showers and thunderstorms surrounding Lane will begin
to spread across the state from the southeast, reaching the Big Island
later this morning. Excessive rainfall is possible which could lead to
major flash flooding, landslides and mudslides. Flooding can occur even
in areas not usually prone to flooding. Storm total rainfall amounts
greater than 20 inches are possible.

Swell generated by Lane will produce very large and rough surf, with
dangerous rip currents along south, southeast and southwest facing
shores.

Tornadoes and large waterspouts will be possible associated with Lane,
mainly along and to the right of the track of the hurricane.

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

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

* SURGE:
Protect against locally hazardous surge having possible limited
impacts across south and west facing coasts. 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.

* WIND:
Protect against life-threatening wind having possible extensive
impacts across across Maui County, Oahu, and western and southern sections
of the Big Island. 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.

Also, protect against dangerous wind having possible significant
impacts across the northern and eastern sections of the Big Island and Kauai.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across the Hawaiian islands. Potential impacts include:
    - The occurrence of isolated tornadoes can hinder the execution
      of emergency plans during tropical events.
    - A few places may experience tornado damage, along with power
      and communications disruptions.
    - Locations could realize roofs peeled off buildings, chimneys
      toppled, mobile homes pushed off foundations or overturned,
      large tree tops and branches snapped off, shallow-rooted trees
      knocked over, moving vehicles blown off roads, and small boats
      pulled from moorings.

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

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

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.

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.

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

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

* 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.

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.

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 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.
