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

Tropical Storm Hone, located about 185 miles southeast of Hilo at 11
AM HST this morning, is forecast to move toward the west for the
next several days, with strengthening expected over the next 24 hours.
Along the forecast track, the center of Hone will pass just south of
the Big Island tonight and Sunday morning and will move off to the
west of the area early next week.

Persistent, moderate rainfall has already developed along windward Big
Island, and as Hone nears, bands of heavy showers and thunderstorms
are expected to intensify this afternoon and tonight, bringing a
threat of flash flooding to the entire Big Island, though the greatest
potential will be across the Hamakua, Hilo, Puna, and Kau Districts.
Storm total rainfall estimates for the Big Island range from 6 to
12 inches with locally higher amounts. A few lingering thundershowers
and heavy showers may persist over portions of Big Island into Monday,
especially over leeward and upslope areas. See the latest Flood Watch
for more details.

Winds associated with Hone will increase over Big Island today and may
become locally damaging by nightfall. Tropical storm conditions, with
sustained winds over 39 mph and gusts in excess of 60 mph, are
expected tonight into early Sunday, especially for areas downslope
from higher terrain, over headlands, 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 today 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.

Preparations for Tropical Storm Hone should be complete.


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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across the Big Island. Potential impacts include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - Rivers and tributaries may quickly become swollen with swifter
      currents and overspill their banks in a few places, especially
      in usually vulnerable spots. Small streams, creeks, canals,
      arroyos, and ditches overflow.
    - Flood waters can enter some structures or weaken foundations.
      Several places may experience expanded areas of rapid
      inundation at underpasses, low-lying spots, and poor drainage
      areas. Some streets and parking lots take on moving water as
      storm drains and retention ponds overflow. Driving conditions
      become hazardous. Some road and bridge closures.

* WIND:
Protect against dangerous wind having possible significant impacts
across the 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.

* SURGE:
Protect against locally hazardous surge having possible limited
impacts across southeast portions of the Big Island. Potential impacts
in this area include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly
      in usually vulnerable locations. Strong rip currents.

Elsewhere across the the Big Island, little to no impact is
anticipated.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across the Big Island. 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.

* OTHER COASTAL HAZARDS:
East swells associated with Hone will bring high and rough surf and
strong rip currents to east and southeast-facing shores of Big
Island, starting later today and persisting 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:

All preparations to protect life and property should be rushed to
completion. Ensure you are in a safe location before the onset of
strong winds or possible flooding.

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.

When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.

Monitor weather.gov, NOAA Weather Radio and local news outlets for
official storm information. Listen for possible changes to the
forecast.
