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.
The main threats from Henri are heavy rain capable of producing flash
flooding, tropical storm force winds along the south shore and east
end of Long Island and across southeast Connecticut, and associated
marine and coastal hazards, including very rough seas and dangerous
rip currents.
A widespread rainfall of 1 to 3 inches is forecast with the potential
of 2 to 4 inches locally higher amounts are 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 scattered areas of flash flooding, particularly for
areas that could see heavy rain Saturday leading into Sunday.
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 dangerous wind having possible significant impacts across
eastern Long Island and Southern Connecticut. 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.
Also, prepare for hazardous 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 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, and
Southern Connecticut, 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:
- 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.
Let others know where you are going prior to departure. Secure
loose items and pets in the car, and avoid distracted driving.
If evacuating, follow designated evacuation routes. Seek traffic
information on roadway signs, on the radio, and from official sources.
* 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 extend well away from the
center of the storm.
If you are a visitor, know the name of the county in which 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 weather.gov, NOAA Weather Radio and local news
outlets for official storm information. Listen for possible changes
to the forecast.
