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

Hurricane Dorian is forecast to pass about 120 miles southeast of
Nantucket Saturday morning as it moves quickly northeastward and well
offshore by late Saturday afternoon. Strong winds, heavy rainfall and
high surf will be the main impacts, with the strongest wind and
heaviest rain occurring late tonight through Saturday morning,
especially over Nantucket. A Tropical Storm Warning remains in effect
for Cape Cod, Marthas Vineyard and Nantucket.

Wind gusts will peak at 40 to 60 mph late tonight and Saturday morning
over the Cape and Islands as winds turn from northeast to north. Winds
will diminish Saturday afternoon. Total rainfall of 2 to 4 inches is
possible with minor urban poor drainage flooding. A storm surge up to 2
feet is possible during the Saturday morning high tide which may bring
minor coastal flooding to Nantucket Harbor, and portions of the coast
of Cape Cod within Cape Cod Bay.

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

* WIND:
Prepare for dangerous wind having possible significant impacts across
      Cape Cod and the islands. 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 the immediate coast of Massachusetts and Rhode Island.

Elsewhere across Southern New England, little to no impact is
anticipated.

* SURGE:
Little to no impacts are anticipated at this time across Southern
New England.

* FLOODING RAIN:
Prepare for locally hazardous rainfall flooding having possible
limited impacts across Cape Cod and the islands. Potential
impacts include:
    - Localized rainfall flooding may prompt a few evacuations.
    - Rivers and tributaries may quickly rise with swifter currents.
      Small streams, creeks, and ditches may become swollen and
      overflow in spots.
    - Flood waters can enter a few structures, especially in usually
      vulnerable spots. A few places where rapid ponding of water
      occurs at underpasses, low-lying spots, and poor drainage
      areas. Several storm drains and retention ponds become
      near-full and begin to overflow. Some brief road and bridge
      closures.

Elsewhere across Southern New England, little to no impact is
anticipated.

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.

Always heed the advice of local officials and comply with orders that
are issued. Do not needlessly jeopardize your life or the lives of
others.

When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.
