SITUATION OVERVIEW
------------------
Tropical Storm Henri is forecast to strengthen to a hurricane as it
heads northward overnight and Saturday. Henri is expected to make
landfall over Long Island on Sunday afternoon and eventually the
central CT coast Sunday evening as a strong Tropical Storm. Henri will
weaken rapidly after landfall, but will exit the region slowly through
Monday. There remains uncertainty in how far west the storm will track
and how strong it will get before making landfall. The main hazards
include damaging winds, flooding rain, and storm surge flooding.
POTENTIAL IMPACTS
-----------------
* WIND:
Prepare for life-threatening wind having possible extensive impacts
across south coastal Rhode Island and Massachusetts. 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 significant impacts
across the rest of southern New England.
* SURGE:
Prepare for life-threatening surge having possible significant
impacts across south coastal Rhode Island and Massachusetts,
including Cape Cod and the Islands. 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.
- Major beach erosion with heavy surf breaching dunes. Strong and
numerous rip currents.
- Moderate damage to marinas, docks, boardwalks, and piers.
Several small craft broken away from moorings, especially in
unprotected anchorages.
Also, prepare for locally hazardous surge having possible limited
impacts along the eastern Massachusetts coastline, north of Sagamore
Beach to the Merrimack River.
* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts across central/western Massachusetts and central/western
Connecticut. Potential impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, and ditches may become
dangerous rivers. In mountain areas, destructive runoff may run
quickly down valleys while increasing susceptibility to
rockslides and mudslides. Flood control systems and barriers
may become stressed.
- 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.
Prepare for dangerous rainfall flooding having possible limited to
significant impacts across southern New England.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Listen to local official for recommended preparedness actions,
including possible evacuation. If ordered to evacuate, do so
immediately.
* 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.
