* WHAT...For the High Surf Advisory, large breaking waves of 10
  to 14 feet in the surf zone. For the first Coastal Flood
  Advisory, up to one foot of inundation above ground level in
  low- lying areas near shorelines and tidal waterways (1.4 to
  13.7 feet Mean Lower Low Water). For the second Coastal Flood
  Advisory, up to one foot of inundation above ground level
  expected in low- lying areas near shorelines and tidal
  waterways (3.9 to 13.3 feet Mean Lower Low Water). For the
  third Coastal Flood Advisory, one to two feet of inundation
  above ground level expected in low- lying areas near
  shorelines and tidal waterways (4.3 to 13.9 feet Mean Lower
  Low Water). For the additional Coastal Flood Advisory, one to
  two feet of inundation above ground level expected in low-
  lying areas near shorelines and tidal waterways (4.4 to 13.7
  feet Mean Lower Low Water).

* WHERE...Eastern Essex MA, Eastern Plymouth MA, Barnstable MA
  and Nantucket MA Counties.

* WHEN...For the High Surf Advisory, until 7 PM EDT Saturday.
  For the first Coastal Flood Advisory, until 6 PM EDT this
  evening. For the second Coastal Flood Advisory, from 11 PM
  this evening to 5 AM EDT Saturday. For the third Coastal Flood
  Advisory, from 11 AM to 5 PM EDT Saturday. For the additional
  Coastal Flood Advisory, from noon to 6 PM EDT Sunday.

* IMPACTS...Most roads remain passable. Flooding up to one foot
  deep affects coastal roads on the North Shore from Salem to
  Gloucester and Newburyport. Rough surf will cause flooding on
  some coastal roads around the time of high tide due to
  splashover. Roads remain passable. Low lying areas and roads
  near Nantucket Harbor, including Easy Street, may experience
  pockets of shallow flooding less than one foot deep. Dangerous
  swimming and surfing conditions and localized beach erosion.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.

Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.
