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

Hurricane Henri will continue moving northward tonight. Henri is
expected to make landfall somewhere between eastern Long Island and
Narragansett Bay as either a strong tropical storm or a lower end
Category 1 hurricane. Henri should weaken rapidly as it heads into
central and northeast Massachusetts Sunday night and Monday. The main
hazards include damaging winds, flooding rain, storm surge flooding,
and possibly a tornado.

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

* WIND:
Protect against 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, protect against dangerous wind having possible significant
impacts across the rest of southern New England.

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across western Massachusetts and most of 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.

Protect against dangerous rainfall flooding having possible limited
to significant impacts across the rest of southern New England.

* SURGE:
Protect against life-threatening surge having possible significant
impacts across south coastal Rhode Island and Massachusetts, especially
on Narragansett Bay and Buzzards Bay shorelines. 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.

* TORNADOES:
Protect against 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:
Keep cell phones well charged. Cell phone chargers for automobiles can
be helpful, but be aware of your risk for deadly carbon monoxide
poisoning if your car is left idling in a garage or other poorly
ventilated area.

If you are a visitor, be sure to know the name of the city or town in
which you are staying and the name of the county in which it resides.
Listen for these locations in local news updates. Pay attention for
instructions from local authorities.

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 cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the local authorities.

Rapidly rising flood waters are deadly. If you are in a flood-prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, turn around don't drown!

If a Tornado Warning is issued for your area, be ready to shelter
quickly, preferably away from windows and in an interior room not
prone to flooding. If driving, scan the roadside for quick shelter
options.

Closely monitor 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.
