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

Tropical Storm Henri is currently due east of the South Carolina
coastline and will likely track north nearing eastern Long Island
and into southern New England Sunday as a Category 1 Hurricane.

The main threats from Henri are potentially life-threatening storm
surge, heavy rain capable of producing flash flooding, tropical
storm or hurricane force winds along the south shore and east end of
Long Island and across southeast Connecticut. There will also be
associated marine and coastal hazards, including very rough seas and
dangerous rip currents.

Severe beach erosion is possible for coastal areas of Long Island
Sound and portions of Suffolk County, including the Twin Forks
region.

A widespread rainfall of 2 to 4 inches is forecast in the path
of Henri with localized higher amounts possible Saturday through
Sunday evening. The highest amounts are forecast to be across
eastern Long Island and much of southeastern Connecticut. This will
present a likelihood for areas of flash flooding.

Dangerous marine conditions are likely on the ocean waters south of Long
Island, as well as on Long Island Sound, and the south shore and
eastern bays of Long Island. Tropical storm force winds will be most
likely in those areas, near the south shores and east end of Long Island
and southeast Connecticut, and in some higher elevations away from the
coastline. Dangerous rip currents and high surf are expected along the
ocean beaches of Long Island beginning Friday.

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

* WIND:
Prepare for life-threatening wind having possible extensive impacts
across eastern Long Island and southern Connecticut. Potential impacts in
this area include:
    - Considerable roof damage to sturdy buildings, with some having
      window, door, and garage door failures leading to structural
      damage. Mobile homes severely damaged, with some destroyed.
      Damage accentuated by airborne projectiles. Locations may be
      uninhabitable for weeks.
    - Many large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. Several bridges, causeways, and
      access routes impassable.
    - Large areas with power and communications outages.

Also, prepare for dangerous wind having possible limited impacts across
southern New York and northeast New Jersey.

* SURGE:
Prepare for locally hazardous surge having possible limited impacts
across coastal Long Island, the Western Long Island Sound, and southern
Connecticut. 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 and frequent rip
      currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

Elsewhere across Southeast New York, Northeast New Jersey, little to no
impact is anticipated.

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across eastern Long Island and southern Connecticut. Potential
impacts include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - Rivers and streams may quickly become swollen with swifter
      currents and may overspill their banks in a few places,
      especially in usually vulnerable spots. Small streams, creeks,
      canals, and ditches may 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.

Prepare for locally hazardous rainfall flooding having possible
limited impacts across southern New York and northeast New Jersey.

* TORNADOES:
Little to no impacts are anticipated at this time
across Southeast New York, Northeast New Jersey, and Southern
Connecticut.

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

* EVACUATIONS:
Listen to local official for recommended preparedness actions, including
possible evacuation. If ordered to evacuate, do so immediately.

For those not under evacuation orders, assess the risk from wind, falling
trees, and flooding at your location. If you decide to move, relocate to
a safer location nearby. If you do not relocate, help keep roadways open
for those under evacuation orders.

If evacuating, leave with a destination in mind and allow extra time to get
there. Take your emergency supplies kit. Gas up your vehicle ahead of time.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.

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 can extend well away from the
center of the storm.

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

Check on those who may not be fully aware of the situation or who are
unable to make personal preparations.

If you are a visitor, know the name of the county where you are
located and where it is relative to current watches and warnings. If
staying at a hotel, ask the management staff about their onsite
disaster plan. Listen for evacuation orders, especially pertaining to
area visitors.

Closely monitor http://weather.gov, NOAA Weather Radio, and local
news outlets for official storm information. Listen for possible
changes to the forecast.
