  protective dune structures. Severe flooding will likely extend
  inland from the waterfront causing flooding of many homes and
  businesses with some structural damage possible. Numerous roads
  will likely be impassable under several feet of water and
  vehicles will likely be submerged. Actions will need to be
  taken to protect life and property. Very dangerous swimming and
  surfing conditions expected, as well as the wave action
  resulting in significant beach erosion.

  with the potential for portions of NC-12 and secondary roads
  along the Outer Banks, in particular on Hatteras and Ocracoke
  Islands, to be impassable and/or inaccessible for several days
  due to significant wave run up. Minor soundside flooding will
  also be possible if stronger winds develop over the Pamlico
  Sound.

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.
