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

Tropical Storm Lala is expected strengthen to a hurricane and bring
damaging winds, heavy flooding rainfall, and dangerously high surf to
portions of the state this weekend. Impacts are expected to begin
tonight on the Big Island of Hawaii, then late tonight into Saturday
morning for Maui County. Oahu and Kauai can expect impacts to begin by
late Saturday afternoon into Saturday evening. Lala is expected to
make landfall over the southern end of the Big Island of Hawaii on
Saturday and pass just south of the rest of the island chain through
Sunday. Damaging winds and heavy rainfall is expected across the
entire state this weekend, with the Big Island of Hawaii likely seeing
the greatest impacts. Do not focus on the exact forecast track or
intensity of Lala at this time, and be prepared for changes in future
forecasts. 

Damaging tropical storm force winds may begin as early as tonight
across parts of the Big Island of Hawaii and Maui County, with
hurricane force winds possible as Lala moves near or over the Big
Island Saturday. Damaging winds are expected to spread westward to
Oahu and Kauai later Saturday afternoon and into Sunday. It is very
important to note that the mountainous terrain of the islands will
likely produce localized areas of highly enhanced and damaging winds,
even well away from the tropical cyclone center.

Flooding rain will be possible as early as tonight on the Big Island
of Hawaii, and Saturday for Maui County. The threat of flooding will
spread to the rest of the state later Saturday and Sunday, and heavy
rainfall could persist into Monday for some areas, mainly over the
western end of the island chain. Lala is expected to produce rainfall
totals of 10 to 20 inches, with locally higher amounts possibly up to
25 inches, across windward Big Island. Rainfall totals of 8 to
12 inches are possible on windward Maui and up to 8 inches of rainfall
could occur across the remainder of the island chain. While the
highest rainfall amounts will be focused over windward areas, leeward
areas will also have a significant flood risk.

Large swells generated by Lala will build tonight and produce
dangerous surf along exposed east and southeast shores of all islands.
Very large and extremely rough seas are expected to rapidly increase
tonight into Saturday on exposed southeast and east shores of the Big
Island and Maui, and then Oahu and Kauai by late Saturday. Damaging
surf, significant beach erosion, and overwash across vulnerable
coastal infrastructure is possible. 

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

* WIND:
Prepare for life-threatening wind having possible extensive impacts 
across the Big Island 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.

Also, prepare for dangerous wind having possible limited to 
significant impacts across the rest of the state.

* SURGE:
Prepare for locally hazardous surge having possible limited impacts 
across Big Island 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.

* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible 
extensive impacts across Big Island of Hawaii and Maui County. 
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 Oahu and Kauai County.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across 
the Big Island. 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 evacuations. If ordered to evacuate, do so 
immediately.

* 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 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.

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.
