 The storm surge and waves from Isabel resulted in another breach between Hatteras and Hatteras Inlet, in an area without roads or houses.The breach nearly became an inlet, though it was not deep enough for a constant water flow; it had little impact on residents.In addition to the floodwaters, Isabel produced an estimated 4 inches (100 mm) of rain throughout most of the Outer Banks, with Duck reporting a peak of 4.72 inches (120 mm).
