High Surf Advisory issued September 24 at 2:08AM EDT until September 27 at 8:00PM EDT by NWS Boston/Norton MA
* WHAT...For the High Surf Advisory, large breaking waves of 6
to 17 feet possible in the surf zone. For the Coastal Flood
Watch, 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 MA, Suffolk MA, Eastern Norfolk MA,
Eastern Plymouth MA, Barnstable MA, Dukes MA and Nantucket MA
Counties.
* WHEN...For the High Surf Advisory, from 5 AM Friday to 8 PM
EDT Sunday. For the Coastal Flood Watch, from Friday afternoon
through Saturday afternoon.
* IMPACTS...Numerous roads may be closed. Low lying property
including homes, businesses, and some critical infrastructure
may be inundated. Some shoreline erosion may occur. Dangerous
swimming and surfing conditions and localized beach erosion.
* 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.
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.
