RALEIGH High winds are causing sound side flooding along N.C. 12, and caused the Hatteras-Ocracoke ferry route to stop operations earlier today. Currently, NC 12 has high water in both directions in areas from Rodanthe to the southern end of Dare County, and is open to high-clearance, four-wheel-drive vehicles only. The Dare County Sheriff's Office has set up a checkpoint in the parking lot of the Pea Island National Wildlife Center just south of the temporary bridge. The road could become completely impassable at high tide.The lanes are not expected to re-open until the storm system moves out of the area and the water recedes. That is expected to be mid-morning, tomorrow, Thursday, March 7. The ferry will begin operating as soon as conditions are safe.Up-to-date information is available by calling 511 or online at www.ncdot.gov/travel. In addition, NCDOT offers travel information on Twitter.Travelers can also call 800-293-3779 (BY-FERRY) and Press 1 for up-to-date ferry information, or sign up to receive Tweets on their personal cell phones by going to www.twitter.com/ncdot_ferry.
