Beach Erosion and Areas of Coastal Flooding Likely

Strong north and northeast winds continue over the region this morning and will actually increase over the course of the day today and into tonight. Wind gusts of 40 to 50 mph are likely at times, especially this afternoon.

The persistent, strong onshore wind is producing large waves and piling up water along our east and north facing shores. A surge of about 1.5 feet was recorded overnight at Sesuit Harbor and about 1 foot at Chatham. A slightly higher value is anticipated during today’s midday high tide, which should lead to some areas of coastal flooding and will very likely cause some substantial beach erosion to the north-facing shores of Cape Cod Bay and along the east-facing coast from Provincetown to Chatham.

An additional round of erosion and spotty coastal flooding is expected tonight and again on Friday as winds only slowly abate tomorrow.
