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

Tropical Storm Henri is forecast to strengthen to a hurricane as it
heads northward today. Henri is expected to make landfall near eastern
Long Island Sunday as either a strong tropical storm or a lower end
Category 1 hurricane. Henri should weaken rapidly as it heads into
Connecticut Sunday evening and slowly exits the region Monday. The main
hazards include damaging winds, flooding rain, storm surge flooding,
and possibly a tornado.

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

* WIND:
Prepare for life-threatening wind having possible extensive impacts
across Connecticut and south coastal Rhode Island. Potential impacts
in this area include:
    - Roof damage to sturdy buildings, with some having window, door,
      and garage door failures leading to structural damage.
    - Many large trees snapped or uprooted.
    - Some roads impassable from large debris, and more within urban or
      heavily wooded places.
    - Power and communications outages.

Also, prepare for dangerous wind having possible limited to
significant impacts across the rest of southern New England.

* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts across western Massachusetts and northern 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 significant
impacts in central Massachusetts and Rhode Island.

* SURGE:
Prepare for life-threatening surge having possible significant impacts
across south coastal Rhode Island and Massachusetts. 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 across east coastal Massachusetts.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across
Southern New England. 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.

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. Plan to have your preparations completed today.

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 live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low-lying or poor
drainage area, in a valley, or near an already swollen river, plan to
move to safe shelter on higher ground.

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.

There is a threat from tornadoes with this storm. Have multiple ways
to receive Tornado Warnings. Be ready to shelter quickly.
