...HIGH SURF ADVISORY IN EFFECT FROM 7 AM TO 7 PM EDT FRIDAY...
...COASTAL FLOOD WATCH IN EFFECT FROM FRIDAY MORNING THROUGH
FRIDAY AFTERNOON...
...HIGH RIP CURRENT RISK IS CANCELLED...
* WHAT...For the High Surf Advisory, large breaking waves
expected in the surf zone. For the Coastal Flood Watch, one to
two feet of inundation above ground level possible in low-lying
areas near shorelines and tidal waterways (4.8 to 14.5 feet Mean
Lower Low Water).
* WHERE...Eastern Essex MA, Eastern Plymouth MA, Barnstable MA
and Nantucket MA Counties.
* WHEN...For the High Surf Advisory, from 7 AM to 7 PM EDT
Friday. For the Coastal Flood Watch, from Friday morning
through Friday afternoon.
* IMPACTS...Some coastal roads become impassable around high
tide. Flooding 1 to 2 feet deep affects roads on the North
Shore from Salem and Marblehead to Gloucester to Newburyport.
Rough surf will cause beach erosion and send and debris onto
coastal roads. Many roads near Nantucket Harbor become
impassable with 1 to 2 feet of water and affects access to the
ferry terminals. This includes Easy Street, South Beach
Street, Easton Street, Walsh Street, Willard Street, and
Straight Wharf. Roads remain passable. Shallow pockets of
flooding less than one foot deep affect low lying areas in
Provincetown, mainly near the airport and Race Point Road. In
Truro, flooding up to one foot deep affects low lying areas
near Pamet Harbor and along the Pamet River. Dangerous
swimming and surfing conditions and localized beach erosion.
* ADDITIONAL DETAILS...Greatest risk of moderate coastal flooding
is along the Plymouth coastline, including the north shore of
Cape Cod (Bay side), from Sandwich to Dennis.
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.

...HIGH RIP CURRENT RISK NOW IN EFFECT THROUGH FRIDAY EVENING...
...COASTAL FLOOD WATCH IN EFFECT FROM FRIDAY MORNING THROUGH
FRIDAY AFTERNOON...
* WHAT...For the High Rip Current Risk, dangerous rip currents.
For the Coastal Flood Watch, up to one foot of inundation
above ground level possible in low-lying areas near shorelines
and tidal waterways (4.2 to 4.7 feet Mean Lower Low Water).
* WHERE...Dukes MA County.
* WHEN...For the High Rip Current Risk, through Friday evening.
For the Coastal Flood Watch, from Friday morning through
Friday afternoon.
* IMPACTS...Roads remain passable with pockets of shallow
flooding less than one foot deep. This mainly affects low
lying areas and roads near Edgartown Harbor, including the
Chappy Ferry Dock. Shallow flooding may also approach Five
Corners in Vineyard Haven. Rip currents can sweep even the
best swimmers away from shore into deeper water.
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.
Swim near a lifeguard. If caught in a rip current, relax and
float. Don't swim against the current. If able, swim in a
direction following the shoreline. If unable to escape, face the
shore and call or wave for help.
