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

Hurricane Hone is located about 100 miles southwest of Kailua-Kona
and 175 miles south-southeast of Honolulu at 11 AM HST this morning.
The center of the storm reached its closest point of approach to the
Big Island around 4am HST, passing approximately 45 miles south-
southwest of South Point, Hawaii. Hone will continue to move toward
the west-northwest on a high-confidence track to the south of the
islands for the next couple of days before leaving the local area by
Tuesday.

Widespread rainfall of 10 to 15 inches has already fallen across
windward Big Island over the past 24 hours, with some locally higher
amounts of 18 inches or more. Rain bands, some heavy, will continue
to move into east through south slopes today, as Hone moves
southwest of the Big Island. Additional rainfall estimates of 3 to 5
inches will keep a moderate to high threat of flash flooding today
over much of Hawaii County, with the greatest potential for flooding
over the Hilo, Puna, and Kau Districts. See the latest Flood Watch
for more details.

Portions of the Big Island continue to observe sustained surface
winds this morning around 30 to 50 mph with gusts up to 60 mph.
Strong, locally damaging, winds will continue over the Big Island
today, especially for areas downslope of higher terrain and through
mountain passes. This includes areas like the Humuula Saddle, the
Waimea Saddle, leeward Kohala, and South Point. Wind speeds will
gradually weaken this evening through tonight.

Large and disorganized short-period swell associated with Hurricane
Hone will bring elevated surf to most east facing shores today. See
the latest High Surf Advisory for more details.

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

* FLOODING RAIN:
Potential impacts from the flooding rain continue to unfold 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 continue to unfold 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 for 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.
