* WHAT...Up to one foot of inundation above ground level
possible in low-lying areas near shorelines and tidal
waterways (3.7 to 12.9 feet Mean Lower Low Water).
* WHERE...Eastern Essex, Suffolk, Eastern Norfolk, Eastern
Plymouth, Barnstable, Dukes and Nantucket Counties.
* WHEN...From Friday afternoon through Saturday afternoon.
* IMPACTS...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.
* ADDITIONAL DETAILS...The exact timing for an approaching
coastal low pressure remains uncertain. That will become
important for peak surge around the times of high tides.
Multiple tide cycles will be impacted, which combined with
strong onshore flow may result in tides not lowering as well.
Beach erosion will also be a concern, mainly for east-facing
beaches.
What to do
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.

Watch
Conditions favor the hazard. Nothing is happening yet; have a plan and be ready to act if a warning follows.
Advisory
A hazard that is less serious than a warning but can still cause trouble, such as dense fog, heat or light ice.
Statement
Information about weather that does not yet meet a warning: a strong storm, a hydrologic update, or a special weather statement.
Severity (extreme, severe, moderate, minor) is the rating the issuing office gives each product. More on the difference: tornado watch vs. tornado warning. Alerts come from the National Weather Service; follow its instructions and your local officials.
