Coastal Flood Warning

Severe

Coastal Flood Warning issued September 26 at 2:00AM EDT until September 27 at 8:00PM EDT by NWS Boston/Norton MA

Issued Until 38 hr 44 min left

Areas Eastern Essex, MA; Suffolk, MA; Eastern Norfolk, MA; Eastern Plymouth, MA; Barnstable, MA; Dukes, MA; Nantucket, MA

Full text

* WHAT...For the Coastal Flood Warning, up to one foot of inundation above ground level in low-lying areas near shorelines and tidal waterways (4.0 to 12.6 feet Mean Lower Low Water). For the High Surf Advisory, large breaking waves of 6 to 13 feet in the surf zone. * WHERE...Eastern Essex MA, Suffolk MA, Eastern Norfolk MA, Eastern Plymouth MA, Barnstable MA, Dukes MA and Nantucket MA Counties. * WHEN...Until 8 PM EDT Sunday. * IMPACTS...Strong northeast winds with large waves will result in minor coastal flooding with pockets of moderate coastal flooding over multiple high tide cycles from late today through the weekend. The water also may struggle to vacate the area after the high tides given persistent strong northeast winds. The greatest risk for coastal flooding appears to be setting up south of Boston and onto the Cape and Islands. In addition...the long duration of northeast winds coupled with large waves over multiple high tide cycles will result in areas of severe beach erosion for a prolonged period.

What to do

Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. Inexperienced swimmers should remain out of the water due to dangerous surf conditions.

What this means

Warning
The hazard is happening or about to. Act now: a tornado warning means take shelter, a flash flood warning means move to higher ground.
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.
