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

Hurricane Nolo is moving slowly northward and will continue to do so
through tonight. Nolo is then forecast to make a sharp turn to the
west on Saturday as it strengthens to a major hurricane. Nolo is
forecast to continue westward through the weekend with the center
passing south of the state. However, impacts from Nolo will be felt
well outside the center of the storm.

Bands of intense showers and thunderstorms associated with Nolo will
affect the Big Island and Maui County over the next couple of days,
beginning later today over the Big Island and Saturday over Maui.
Excessive rainfall is possible which could lead to locally
catastrophic flash flooding and mudslides across windward and
southeast Big Island. Flooding can occur even in areas not usually
prone to flooding. Additional rainfall amounts of 10 to 15 inches
are possible on the Big Island, with localized higher amounts of 20
inches. On Maui, additional rainfall amounts of 4 to 8 inches are
possible, with localized higher amounts of 15 inches. Outer rain
bands associated with Nolo could reach the other smaller islands,
and would be enhanced by the terrain.

Tropical storm force winds are expected to reach the Big Island as
early as this afternoon, with hurricane force winds possible by late
tonight. The earliest reasonable time of arrival for tropical storm
force winds is predawn Saturday for Maui County. A Tropical Storm
Warning and Hurricane Watch is in effect for Big Island, and a
Tropical Storm Watch is in effect for the islands of Maui County. A
Wind Advisory has been issued for the rest of the state.

Swell generated by Nolo could bring very large and rough surf and
dangerous rip currents for south and southeast facing shores,
especially for the Big Island. A High Surf Advisory remains in
effect for south and east facing shores of Big Island and east
facing shores of Maui and Molokai. A High Surf Advisory has also
been issued for east facing shores of Niihau, Kauai, and Oahu
beginning tonight.

Tornadoes and large waterspouts will be possible associated with
Nolo, mainly over and near the Big Island, along and to the right of
the track of the tropical cyclone.

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

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across east and southeast Big Island. 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.

Protect against life-threatening rainfall flooding having possible
limited to extensive impacts across northwest Big Island and Maui Island.

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

* WIND:
Protect against dangerous wind having possible significant impacts
across Big Island. Potential impacts in this area include:
- Some damage to roofing and siding materials, along with damage
to porches, awnings, carports, and sheds. A few buildings
experiencing window, door, and garage door failures. Mobile
homes damaged, especially if unanchored. Unsecured lightweight
objects become dangerous projectiles.
- Several large trees snapped or uprooted, but with greater
numbers in places where trees are shallow rooted. Several
fences and roadway signs blown over.
- Some roads impassable from large debris, and more within urban
or heavily wooded places. A few bridges, causeways, and access
routes impassable.
- Scattered power and communications outages, but more prevalent
in areas with above ground lines.

Also, protect against hazardous wind having possible limited impacts
across the rest of the main Hawaiian Islands.

* SURGE:
Protect against locally hazardous surge having possible limited
impacts across Big Island. 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.

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

* TORNADOES:
Protect against 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:
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.

Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the 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 a Tornado Warning is issued for your area, be ready to shelter
quickly, preferably away from windows and in an interior room not
prone to flooding. If driving, scan the roadside for quick shelter
options.

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.
