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

The center of Hurricane Hector is expected to pass 150 miles south
of the Big Island on Wednesday. However,the effects of a hurricane
extend well away from the center of the storm.

Strong winds are expected to develop on Wednesday, with the strongest
winds expected over and downwind of the higher terrain of the Big
Island.

Surf along east facing shores is building and is expected to peak
late tonight through Wednesday. Expect surf heights of 12 to 15 feet
mainly for the Puna and Kau districts of the Big Island. High surf
will combine with seasonably high tides producing overwash on low-lying
coastal areas and roadways, with potential for coastal erosion impacts
as well.

Enhanced rainfall from deep tropical moisture surrounding Hector
will affect the Puna, Kau, North Hilo, and South Hilo Districts of
the Big Island as the hurricane passes by south of the state over the
next couple of days. Rain showers may be locally heavy at times,
particularly over east to southeast facing slopes.

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

* WIND:
Protect against hazardous wind having possible limited impacts across
the Big Island. Potential impacts in this area 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.

Elsewhere across the Hawaiian islands, little to no impact is
anticipated.

* FLOODING RAIN:
Protect against locally hazardous rainfall flooding having possible
limited impacts across Puna, Kau, North Hilo, and South Hilo Districts.
Potential impacts include:
    - Localized rainfall flooding may prompt a few evacuations.
    - Rivers and tributaries may quickly rise with swifter currents.
      Small streams, creeks, canals, arroyos, and ditches may become
      swollen and overflow in spots.
    - Flood waters can enter a few structures, especially in usually
      vulnerable spots. A few places where rapid ponding of water
      occurs at underpasses, low-lying spots, and poor drainage
      areas. Several storm drains and retention ponds become
      near-full and begin to overflow. Some brief road and bridge
      closures.

Elsewhere across the Hawaiian islands, little to no impact is
anticipated.

* OTHER COASTAL HAZARDS:
Prepare for locally hazardous high surf with coastal impacts along east
facing shores of the Big Island. Higher tides during the afternoon on
Wednesday will increase the possibility of coastal inundation, due to a
combination of high surf and high tides.

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

* EVACUATIONS:
Listen to local official for recommended preparedness actions,
including possible evacuation. 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.

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 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.
