Situation overview
------------------

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

The onset of damaging tropical storm force winds on The Big Island
could be as early as Wednesday afternoon or evening, with dangerous
hurricane force winds possible by Wednesday night. On Maui County,
damaging tropical storm force winds could begin as early as Wednesday
night, with dangerous hurricane force winds possible starting on
Thursday. Hurricane watches may be needed for other areas as Lane draws
closer.

Bands of intense showers and thunderstorms surrounding Lane will begin
to overspread the state from south to north, reaching The Big Island
late tonight or Wednesday 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 bring very large and rough surf and
dangerous rip currents for south and southeast 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
-----------------

* wind:
prepare for life-threatening wind having possible extensive impacts
across Oahu, Maui, Molokai, Lanai and 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, prepare for dangerous wind having possible significant impacts
across on Kauai and Niihau.

* Flooding rain:
prepare for life-threatening rainfall flooding having possible
devastating impacts across the main 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.

* Tornadoes:
prepare for 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 check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.

When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.

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, plan to move to safe shelter.

If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large Inland Lake, in a low-lying or poor
drainage area, in a valley, or near an already swollen river, plan to
move to safe shelter on higher ground.

Always heed the advice of local officials and comply with orders that
are issued. Do not needlessly jeopardize your life or the lives of
others.

When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.

Be sure to let friends and family members know of your intentions for
weathering the storm and your whereabouts. Have someone located away
from the threatened area serve as your Point of contact. Share vital
contact information with others. Keep cell phones handy and charged.

Check on those who may not be fully aware of the situation or who are
unable to make personal preparations.

If you are a visitor, know the name of the island on which you are
staying and where it is relative to current watches and warnings. If
staying at a hotel, ask the management staff about their onsite
disaster plan. Listen for evacuation orders, especially pertaining to
area visitors.

Closely monitor weather.Gov, NOAA Weather Radio and local news
outlets for official storm information. Listen for possible changes
to the forecast.

There is a threat from tornadoes with this storm. Have multiple ways
to receive tornado warnings. Be ready to shelter quickly.

High Surf Warning, Flash Flood Watch
Issued: 4:08 PM HST Aug. 21, 2018 – National Weather Service

... High surf warning in effect until 6 am HST Friday...
... High surf advisory is cancelled...

The National Weather Service in Honolulu has issued a high surf
warning, which is in effect until 6 am HST Friday. The high surf
advisory has been cancelled.

* Surf... 15 to 25 feet with locally higher waves along south
facing shores of The Big Island with the largest waves expected
along the south and the southeast coast of The Big Island.

* Timing... tonight through Thursday night.

* Impacts... extreme... expect ocean water surging and sweeping over
beaches, coastal benches, lava flows, and roadways, creating the
potential for significant damage to coastal properties and
infrastructure, including roadways. Coastal evacuations and Road
closures are possible. Large breaking waves may affect Harbor
entrances and channels with significant damage possible to
docks, piers, ramps, and boats.

Precautionary/preparedness actions...

Due to potential hazards and emergency vehicle operations, travel
in coastal areas and ocean recreation should be avoided. Large
breaking surf, significant shorebreak, and dangerous currents make
entering the water extremely hazardous. Anyone entering the water
could face significant injury or death.







541 am HST Tue Aug 21 2018

... A Flash Flood Watch has been issued for the state of Hawaii...

Latest forecast models indicate that, regardless of the eventual
track and intensity of Lane, an extremely moist and unstable air
mass will move over the islands beginning Wednesday morning, and
will remain in place through the end of the week. This is expected
to result in very heavy rainfall, potentially leading to flash
flooding.

Higher confidence in the heavy rainfall and flooding threat from
Hurricane Lane has led to the issuance of a Flash Flood Watch for
the state of Hawaii at 5 am HST.

This will be the final hydrologic outlook issued for this event.
Further hydrologic threat information will be covered by flash
flood watches, flash flood warnings and flood advisories as
conditions warrant.

539 am HST Tue Aug 21 2018

... Flash Flood Watch in effect from Wednesday morning through
Friday afternoon...

The National Weather Service in Honolulu has issued a

* Flash Flood Watch for Kahoolawe, Kauai, Lanai, Maui, Molokai,
Niihau, Oahu and The Big Island.

* From Wednesday morning through Friday afternoon

* abundant moisture from Hurricane Lane is expected to move over
The Big Island late Wednesday and spreading to the rest of the
islands through Friday. Intense rainfall will be possible,
especially along southeast and east facing slopes. The risk of
flooding will only increase as Hurricane Lane approaches.

* In addition to flood prone areas, heavy rain events of this size
may cause flooding in areas outside of designated flood zones.
Low spots in roads will become dangerous and impassible due to
severe runoff. High amounts of debris in streams and gulches may
clog bridges and culverts resulting in dangerous flooding
outside the normal channels and significant property damage.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.

          Rough surf, coastal erosion, and life-threatening rip
          currents are possible.
        - Prepare: little to no preparations for storm surge flooding
          are needed.
        - Act: follow the instructions of local officials. Monitor
          forecasts.

    - Potential impacts: little to none
        - little to no potential impacts from storm surge flooding.

* Flooding rain
    - latest local forecast: Flash Flood Watch is in effect
        - peak rainfall amounts: additional more than two feet

    - potential threat to life and property: potential for extreme
      flooding rain
        - the flooding rain threat has remained nearly steady from
          the previous assessment.
        - Plan: emergency plans should include the potential for
          extreme flooding from heavy rain. Evacuations and rescues
          are likely.
        - Prepare: urgently consider protective actions from extreme
          and widespread rainfall flooding.
        - Act: heed any flood watches and warnings. Failure to take
          action will likely result in serious injury or loss of life.

    - Potential impacts: devastating to catastrophic
        - 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.

* Tornado
    - latest local forecast:
        - situation is somewhat favorable for tornadoes

    - potential threat to life and property: potential for a few
      tornadoes
        - the tornado threat has remained nearly steady from the
          previous assessment.
        - Plan: emergency plans should include the potential for a
          few tornadoes.
        - Prepare: if your shelter is particularly vulnerable to
          tornadoes, prepare to relocate to safe shelter before
          hazardous weather arrives.
        - Act: if a Tornado Warning is issued, be ready to shelter
          quickly.

    - Potential impacts: limited
        - 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.

High Surf Warning, Flash Flood Watch
Issued: 4:08 PM HST Aug. 21, 2018 – National Weather Service

... High surf warning in effect until 6 am HST Friday...
... High surf advisory is cancelled...

The National Weather Service in Honolulu has issued a high surf
warning, which is in effect until 6 am HST Friday. The high surf
advisory has been cancelled.

* Surf... 15 to 25 feet with locally higher waves along south
facing shores of The Big Island with the largest waves expected
along the south and the southeast coast of The Big Island.

* Timing... tonight through Thursday night.

* Impacts... extreme... expect ocean water surging and sweeping over
beaches, coastal benches, lava flows, and roadways, creating the
potential for significant damage to coastal properties and
infrastructure, including roadways. Coastal evacuations and Road
closures are possible. Large breaking waves may affect Harbor
entrances and channels with significant damage possible to
docks, piers, ramps, and boats.

Precautionary/preparedness actions...

Due to potential hazards and emergency vehicle operations, travel
in coastal areas and ocean recreation should be avoided. Large
breaking surf, significant shorebreak, and dangerous currents make
entering the water extremely hazardous. Anyone entering the water
could face significant injury or death.







541 am HST Tue Aug 21 2018

... A Flash Flood Watch has been issued for the state of Hawaii...

Latest forecast models indicate that, regardless of the eventual
track and intensity of Lane, an extremely moist and unstable air
mass will move over the islands beginning Wednesday morning, and
will remain in place through the end of the week. This is expected
to result in very heavy rainfall, potentially leading to flash
flooding.

Higher confidence in the heavy rainfall and flooding threat from
Hurricane Lane has led to the issuance of a Flash Flood Watch for
the state of Hawaii at 5 am HST.

This will be the final hydrologic outlook issued for this event.
Further hydrologic threat information will be covered by flash
flood watches, flash flood warnings and flood advisories as
conditions warrant.

... Flash Flood Watch in effect from Wednesday morning through
Friday afternoon...

The National Weather Service in Honolulu has issued a

* Flash Flood Watch for Kahoolawe, Kauai, Lanai, Maui, Molokai,
Niihau, Oahu and The Big Island.

* From Wednesday morning through Friday afternoon

* abundant moisture from Hurricane Lane is expected to move over
The Big Island late Wednesday and spreading to the rest of the
islands through Friday. Intense rainfall will be possible,
especially along southeast and east facing slopes. The risk of
flooding will only increase as Hurricane Lane approaches.

* In addition to flood prone areas, heavy rain events of this size
may cause flooding in areas outside of designated flood zones.
Low spots in roads will become dangerous and impassible due to
severe runoff. High amounts of debris in streams and gulches may
clog bridges and culverts resulting in dangerous flooding
outside the normal channels and significant property damage.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.
