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

Hurricane Dorian is forecast to pass about 150 miles south of

Strong winds, heavy rainfall and high surf will be the main impacts,
with the strongest wind and heaviest rain occurring late Friday night
into early Saturday. Tropical storm watches have been issued for Cape
Cod and Nantucket.

North winds will increase to 30 to 40 mph late Friday night over
Nantucket and the outer Cape with occasional gusts to 60 mph possible.
Total rainfall of 2 to 4 inches is possible with minor urban poor
drainage flooding. A storm surge of 2 to 2.5 feet is possible during
the Saturday morning high tide which may bring minor coastal flooding
to Nantucket Harbor.

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

* WIND:
Prepare for dangerous wind having possible significant impacts across
Cape Cod and the Islands. Potential impacts in this area include:
    - Downed trees and power lines.
    - Some roads impassable from large debris, and more within urban or
      heavily wooded places.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines.

Also, prepare for hazardous wind having possible limited impacts
across southeast MA.

* SURGE:
Minor coastal flooding is possible along Nantucket Harbor during the
high tide Saturday morning.

* FLOODING RAIN:
Prepare for locally hazardous rainfall flooding having possible limited
impacts across Cape Cod and the Islands. Potential impacts include:
    - 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.
