Erosion along the Outer Beach from Eastham to Provincetown on the Cape was severe, with waves up to 15 feet high crashing directly against the dune cliffs by 11:30 a.m., more than an hour before scheduled high tide. They were still hammering against the cliffs at 2 p.m., according to National Park Service spokesman David Crary, who was monitoring Cape Cod National Seashore Ranger reports from the park headquarters in South Wellfleet.

Further out on the Outer Cape, high winds tore away a section of the roof of the Highland House in North Truro, which is listed on the National Historic Register, according to a spokesman for Cape Cod National Seashore.

No section of the region was spared: Residents were asked to consider leaving their homes in the Common Fields section of Barnstable off Route 6-A on the north side of the Cape near Cape Cod Bay, and also in the South Cape Beach area of Mashpee on the south coast of the Cape, facing Nantucket Sound.
