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

Hurricane Hone, located about 115 miles southwest of Hilo and 240
miles south-southeast of Honolulu at 5 AM HST this morning.
Hurricane Hone will continue to move westward on a high confidence
track for the next several days. At 4 am HST this morning, Hurricane
Hone reached its closest point of approach to the Big Island passing
approximately 45 miles south-southwest of South Point, Hawaii.
Hone will move west of the area over the next few days.

Rainfall of 6 to 10 inches has already fallen across windward Big
Island over the past 18 to 24 hours, and shower bands continue to
move into the east and southeast slopes as Hone brushes past the Big
Island. Bands of additional heavy showers will keep a moderate to
high threat of flash flooding today over Hawaii County. The greatest
potential for flooding will be across the eastern and southeastern
windward slopes of the Big Island; including the Hamakua, Hilo,
Puna, and Kau Districts. Additional rainfall estimates over these
areas through Monday will range from 3 to 6 inches. See the latest
Flood Watch for more details.

Portions of the Big Island continue to observe sustained surface
winds this morning around 30 to 40 mph and gusts over 50 mph, while
a few sites in and around Kohala Ranch have gusted over 60 mph.
Strong locally damaging winds will continue over the Big Island
through the morning with sustained winds over 40 mph and gusts in
excess of 60 mph, especially for areas downslope from higher terrain
and through passes. This includes areas like the Humuula Saddle, the
Waimea Saddle, leeward Kohala, and South Point. Wind speeds will
then weaken over the island from the afternoon through the evening
hours.

Large and disorganized short period swell associated with Hurricane
Hone will bring elevated surf to east and southeast facing shores today.
A High Surf Advisory is in effect east facing shores of the Big Island.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are now unfolding across the
Big Island. Remain well guarded against life-threatening flood waters
having possible extensive impacts, mainly over windward areas. If
realized, these 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.

* WIND:
Potential impacts from the main wind event are now unfolding across
the Big Island. Remain well sheltered from dangerous wind having
possible significant impacts. If realized, these impacts 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.

* OTHER COASTAL HAZARDS:
Large and disorganized short period swell associated with Hurricane
Hone will bring elevated surf to east and southeast facing shores today.
A High Surf Advisory is in effect east facing shores of the Big Island.

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

* EVACUATIONS:
Follow the advice of local officials

* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside. Listen for updates and be ready in
case you lose electrical power. Keep a battery-powered radio,
charged cell phone and flashlight handy.

When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.

If you live in a place particularly vulnerable to flooding, such as
a low-lying or poor drainage area, plan to move to safe shelter on
higher ground.
