...COASTAL FLOOD WARNING REMAINS IN EFFECT UNTIL NOON EDT TODAY...
* LOCATION...Ocean-exposed shoreline from Hull to Plymouth. Cape
Cod Bay shoreline from Sandwich to Dennis. Cape Cod ocean side
from Truro to Chatham. Nantucket, including both the harbor
area and the east side.
* TIDAL DEPARTURE...3 to 3.5 feet above the predicted
astronomical tide, highest along north and east facing
shorelines of Cape Cod and Nantucket.
* TIMING...During the morning high tide between 8 AM and noon.
* COASTAL FLOOD IMPACTS...Minor to moderate coastal flooding is
likely Hull to Plymouth and Sandwich to Dennis. Areas of
moderate coastal flooding is forecast for the ocean side of
Cape Cod, Nantucket Harbor, and the east side of Nantucket.
There may be pockets of inundation of around two feet,
especially where seawalls, dunes, and other protective
shoreline structures have been compromised.
* SHORELINE IMPACTS...Severe erosion is likely from the surf
about the morning high tide, especially along the ocean side
of Cape Cod and the Nantucket east side. Waves will rapidly
build to between 15 and 20 feet across Stellwagen Bank and
Massachusetts Bay and 20 to 30 feet east of Cape Cod and
Nantucket by the time of the morning high tide.
&&
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.
