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

Henri remains a Category 1 hurricane and is currently 80 miles
south southeast of Montauk Point. Henri is expected to decrease in 
forward speed and turn toward the north-northwest this morning. On this
forecast track, Henri is expected to make landfall between the vicinity
of Montauk NY and Narragansett Bay late this morning or early this 
afternoon at or near hurricane strength. After landfall, rapid 
weakening is expected.

Henri will then track into southern New England late today into Monday
as it further weakens. 

The main threats from Henri continue to be potentially life-
threatening storm surge, heavy rain capable of producing flash
flooding, tropical storm or hurricane force winds along the south 
shore of Long Island and across southern 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.

Widespread rainfall potential of 5 to 10 inches today through Monday
evening for the Lower Hudson Valley and parts of Southern Connecticut
and 3 to 6 inches for elsewhere in the forecast region. Locally higher
amounts will be possible. 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. Dangerous rip currents and high surf are
expected along the ocean beaches of Long Island.

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

* WIND:
Protect against 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, protect against dangerous wind having possible limited to 
significant impacts across New York City metro area, portions of the 
Lower Hudson Valley, and portions of northeastern New Jersey.

* SURGE:
Protect against life-threatening surge having possible significant
impacts across all coastal areas of Long Island Sound, and much of the
Great South Bay and southeast coast of Long Island. Potential impacts 
in this area include:
    - Areas of inundation with storm surge flooding accentuated by 
      waves. Damage to several buildings, mainly near the coast.
    - Sections of near shore escape routes and secondary roads become 
      weakened or washed out, especially in usually vulnerable low 
      spots. Flood control systems and barriers may become stressed.
    - Major beach erosion with heavy surf breaching dunes. Very 
      dangerous surf and rip currents.
    - Moderate damage to marinas, docks, boardwalks, and piers. 
      Several small craft broken away from moorings, especially in 
      unprotected anchorages.

Also, protect against locally hazardous surge having possible limited 
impacts across Jamaica Bay, and New York Harbor.

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

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible 
extensive impacts across Southeast New York, Northeast New Jersey, 
and Southern Connecticut. Potential impacts include:
    - Major rainfall flooding may prompt many evacuations and rescues.
    - Rivers and streams may rapidly overflow their banks in multiple 
      places. Small streams, creeks, canals, and ditches may become 
      dangerous rivers. Flood control systems and barriers may become 
      stressed.
    - In hilly terrain, destructive runoff may run quickly down 
      valleys, and increase susceptibility to rockslides and 
      mudslides. 
    - 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.

* TORNADOES:
Protect against a tornado event having possible limited impacts across
eastern Long Island and southeast Connecticut. 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.
    - Locations could realize roofs peeled off buildings, chimneys 
      toppled, mobile homes pushed off foundations or overturned, 
      large tree tops and branches snapped off, shallow rooted trees 
      knocked over, moving vehicles blown off roads, and small boats 
      pulled from moorings.

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

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.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to complete all preparations to protect life and 
property in accordance with your emergency plan. Make sure you are in a
safe location before the onset of strong winds or possible flooding.

If you are relocating to safe shelter, leave as early as possible. 
Allow extra time to reach your destination. Many roads and bridges 
may be closed once strong winds arrive. Check the latest weather 
forecast before departing and drive with caution.

Failure to adequately shelter may result in serious injury or loss of 
life. Always heed the advice of local officials and comply with any 
orders that are issued. Remember that during the storm 9 1 1 
Emergency Services may not be able to immediately respond if 
conditions are unsafe. This should be a big factor in your decision 
making.

Keep cell phones well charged. Cell phone chargers for automobiles 
can be helpful, but be aware of your risk for deadly carbon monoxide 
poisoning if your car is left idling in a garage or other poorly 
ventilated area.

Storm surge is the leading killer associated with tropical storms and 
hurricanes! Make sure you are in a safe area away from the surge 
zone. Even if you are not in a surge prone area, you could find 
yourself cut off by flood waters during and after the storm. Heed 
evacuation orders issued by local authorities.

Rapidly rising flood waters are deadly. If you are in a flood prone 
area, consider moving to higher ground. Never drive through a flooded 
roadway. Remember, Turn Around Don't Drown!

If a Tornado Warning is issued for your area, be ready to shelter 
quickly, preferably away from windows and in an interior room not 
prone to flooding. If driving, scan the roadside for quick shelter 
options.

If in a place that is vulnerable to high winds, such as near large 
trees, a mobile home, upper floors of a high rise building, or on a 
boat, consider moving to a safer shelter before the onset of strong 
winds or flooding.

Closely monitor http://weather.gov, NOAA Weather radio or local news 
outlets for official storm information. Be ready to adapt to possible 
changes to the forecast. Ensure you have multiple ways to receive 
weather warnings.
