SITUATION OVERVIEW
------------------
Tropical Storm Henri is currently 615 miles south of Montauk Point
and will likely track north across 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 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.
A widespread rainfall of 3 to 6 inches is forecast in the path of
Henri with localized higher amounts possible Saturday through Sunday
night. The highest amounts are forecast to be across eastern Long
Island and much of southern 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. Hurricane force winds will be most likely
in those areas. Dangerous rip currents and high surf are expected
along the ocean beaches of Long Island beginning Friday.
POTENTIAL IMPACTS
-----------------
* WIND:
Protect against life-threatening wind having possible devastating
impacts across eastern Long Island and southern Connecticut.
Potential impacts in this area include:
- Structural damage to sturdy buildings, some with complete roof
and wall failures. Complete destruction of mobile homes. Damage
greatly accentuated by large airborne projectiles. Locations
may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and
roadway signs blown over.
- Many roads impassable from large debris, and more within urban
or heavily wooded places. Many bridges, causeways, and access
routes impassable.
- Widespread power and communications outages.
Also, protect against life-threatening wind having possible
significant to extensive impacts across the New York City
metro, 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 Long Island 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.
Protect against dangerous rainfall flooding having possible
significant impacts across northeastern New Jersey, New York City,
and the lower Hudson Valley.
* TORNADOES:
Little to no impacts are anticipated at this time
across Southeast New York, Northeast New Jersey, and Southern
Connecticut.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
WATCH/WARNING PHASE - Listen to local official for recommended
preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.
WATCH/WARNING PHASE - 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:
Saturday 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.
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.
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.
