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

Hone has strengthened into a Hurricane with the latest forecast,
located about 110 miles south of Hilo and 270 miles southeast of
Honolulu at 11 PM HST this evening. Hurricane Hone will continue to
move on a high confidence westward track for the next several days.
Along the forecast track, the center of Hone will pass just south of
South Point on the Big Island by Sunday morning and will then move
west of the area early next week.

Rainfall of 3 to 6 inches has already fallen across windward Big
Island over the past 12 to 18 hours, and heavier showers are moving
in as Hone bushes past the Big Island. Bands of additional heavy
showers and thunderstorms will affect the entire Big Island,
increasing the threat of flash flooding into Sunday. The greatest
potential for flooding will be across the eastern and southeastern
slopes of the Big Island; including the Hamakua, Hilo, Puna, and Kau
Districts. Storm total rainfall estimates through Sunday over the
Big Island range from 6 to 12 inches with locally higher amounts. A
few lingering thunderstorms and heavy showers may develop over
portions of Big Island on Monday, mainly over leeward and upslope
areas. See the latest Flood Watch for more details.

Portions of the Big Island continue to observe sustained surface
winds 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 winds
will continue through the morning hours and will likely become
locally damaging. Sustained winds over 40 mph and gusts in excess of
60 mph, are expected for portions of the Big Island, 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.

Large short period swell produced by Hone will build through the
evening and peak tonight, mainly along east and southeast showers of
the Big Island. The large swells will spread across the other
portions of the island chain tonight and Sunday, producing life-
threatening surf and rip currents. A High Surf Warning is in effect
for 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.

* TORNADOES:
Potential impacts from tornadoes are now unfolding across the Big
Island. Remain well braced against a tornado event having possible
limited impacts. If realized, these 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.

* OTHER COASTAL HAZARDS:
East to southeast swells associated with Hone will bring high and
rough surf and strong rip currents to east and southeast-facing shores
of Big Island into Sunday. A High Surf Warning is in effect for east
and southeast facing shores of 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.
