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

Hurricane Lane is passing to the south-southeast of The Big Island
this morning and is expected to make a turn toward the islands
Wednesday into Thursday.

The onset of damaging tropical storm force winds on The Big Island
could be as early as Wednesday, 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 could 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 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 on Oahu,
Maui, Molokai, Lanai, and Kahoolawe. 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 officials for recommended preparedness actions, including
possible evacuation. If ordered to evacuate, do so immediately.

* 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, 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 located 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.

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

Hurricane Lane is expected to turn northwest toward the main
Hawaiian islands later this week. As Lane approaches The Big Island the
south through west sections of the island may experience tropical
storm conditions with winds 30 mph or greater starting on Wednesday night.

Deep tropical moisture associated with Lane will spread across all
islands. Expect periods of heavy rainfall, especially along the
southeast and east facing slopes. Storm total rainfall amounts of
10 to 15 inches with local amounts greater than 20 inches possible.

Swell generated by Lane could bring very large and rough surf
and dangerous rip currents for south and southeast facing shores.

Potential impacts
-----------------

* wind:
prepare for hazardous wind having possible limited impacts across the
Hawaiian islands. Potential impacts include:
    - damage to porches, awnings, carports, sheds, and unanchored
      Mobile homes. Unsecured lightweight objects blown about.
    - Many large tree limbs broken off. A few trees snapped or
      uprooted, but with greater numbers in places where trees are
      shallow rooted. Some fences and roadway signs blown over.
    - A few roads impassable from debris, particularly within urban
      or heavily wooded places. Hazardous driving conditions on
      bridges and other elevated roadways.
    - Scattered power and communications outages.

* Flooding rain:
prepare for life-threatening rainfall flooding having possible
extensive impacts across Maui County and Hawaii County. The highest
threat of heavy rainfall and flooding is expected along southeast Big Island.
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.

Prepare for dangerous rainfall flooding having possible limited to
significant impacts across Maui and Hawaii County.

* Tornadoes:
little to no impacts are anticipated at this time
across the Hawaiian islands.

* Other coastal hazards:
prepare for locally hazardous high surf with coastal impacts along
south and southeast facing shores of Maui and Hawaii County.

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

Flash Flood Watch
Issued: 5:41 AM HST Aug. 21, 2018 – National Weather Service

... 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.

          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

Flash Flood Watch
Issued: 5:41 AM HST Aug. 21, 2018 – National Weather Service

... 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.
