...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 3 PM EDT THIS
AFTERNOON...

* LOCATIONS...Suffolk MA, Eastern Essex MA, Eastern Norfolk MA 
  and Eastern Plymouth MA.

* TIMING...Until 3 PM EDT this afternoon.

* COASTAL FLOOD IMPACTS...Widespread minor coastal flooding is
  expected during the early afternoon high tide. The main impacts
  will be some typically vulnerable shoreline roads becoming
  flooded and perhaps impassable for a time within an hour or two
  on either side of high tide.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Coastal Flood Advisory is issued for minor coastal flooding of
the most vulnerable shore roads and/or basements due to the
height of storm tide or wave splashover. The majority of roads
remain passable with only isolated closures. There is no
significant threat to life...and impact on property is minimal.

&&

Time of high total tides are approximate to the nearest hour.
Category thresholds are based on still water levels. Impacts 
may be greater, depending upon wave action.
