    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 starting to begin on
    the Big Island of Hawaii tonight, then will spread into Maui County
    late tonight into Saturday morning. Oahu and Kauai can expect impacts
    to begin by late Saturday afternoon into Saturday evening. Lala is
    expected to pass or 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 will begin 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 tonight on the Big Island of Hawaii,
    but the threat of flash flooding will quickly ramp up on Saturday as
    Lala approaches. The threat for flooding will begin over Maui County
    on Saturday and spread to the rest of the state later Saturday and
    Sunday. 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:
    Follow the advice of local officials

    * 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.

    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.
