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

Henri is now a tropical storm, with maximum sustained winds of 70 
mph. The center of Henri is currently 40 miles south-southeast of 
Montauk Point, and is moving north-northwest at 16 mph. On this 
track the center of Henri will likely pass very close to Montauk 
Point late this morning. and then track into southern New England 
through Monday while weakening. 

The main threats from Henri continue to be potentially life-
threatening storm surge, heavy rain capable of producing flash 
flooding, and tropical storm 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, 
high surf, and 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 of 3 to 6 inches is forecast in the path of 
Henri with localized higher amounts possible. The highest amounts 
are forecast to occur across Long Island and much of southern 
Connecticut. 

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:
Potential impacts from the main wind event are now unfolding across 
eastern Long Island and southeast Connecticut. 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.

* SURGE:
Potential impacts from the main surge event are now unfolding across 
the shorelines of Long Island Sound, much of the Great South Bay, and
eastern Long Island. Remain well away from life-threatening surge
having possible significant impacts. If realized, these impacts 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. 

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across 
Southeast New York, Northeast New Jersey, and Southern Connecticut. 
Remain well guarded against life-threatening flood waters having 
additional extensive impacts. If realized, these 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 downhill 
      and increase susceptibility to rockslides. 
     - 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:
Potential impacts from an isolated tornado or two are still unfolding
across southeast Connecticut and eastern Long Island as rain bands move
onshore. Remain prepared for a tornado event having possible 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.
    - 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.

* OTHER COASTAL HAZARDS:
High surf, dangerous rip currents, beach flooding, dune erosion, and
localized overwashes are all expected along the south shore of Long
Island, especially across eastern Suffolk County. 

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

* EVACUATIONS:
Listen to local officials 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. Follow designated evacuation routes. Seek traffic information
on roadway signs, on the radio, and from official sources. Let others
know where you are going prior to departure. Secure loose items and
pets in the car, and avoid distracted driving. 

Do not enter evacuated areas until officials have given the all clear
to return. 

* OTHER PREPAREDNESS INFORMATION:

Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a battery
powered radio, charged cell phone and flashlight handy.

During the peak of the storm be ready to move quickly. Keep your 
shoes on and rain gear handy. Boots and athletic shoes offer the best 
foot protection if you become unexpectedly exposed to the weather.

Keep your cell phone charged and in power saving mode. If you lose 
power, use it sparingly and mainly for personal emergencies and 
checkins.

If you are prone to flooding or in an area under a storm surge watch 
or warning, be prepared for the possibility of a quick and dramatic 
rise in water levels.

If a tornado warning is issued for your area, quickly move to the 
safest place within your shelter. Protect your head and body.
