As of Sunday September 30 I spoke to Osprey Marina. The Waccamaw had crested at nearly 3 feet above the previous record but is going down. The marina is closed. Socastee Bridge is still closed and will be for quite a while. The USCG exclusion zone has been reduced to about 30 miles from about about mile 365 north of Socastee, on south in the Waccamaw River. Winyah Bay and Georgetown are now open and do not need a USCG transit permission. Boats may enter and continue south in the ICW.
I have spoken to one boat now in Beaufort SC who left Myrtle Beach at Little Rive inlet and reentered at Winyah Bay. They report that from Winyah Bay south there are no unusual problems. Conditions appear to be as they were during the northward migration in 2018.
I have spoken to a couple of boats who have made it to Myrtle Beach and found the ICW to be passable. They are all about 4.5 foot of draft and none reported the stated or reported the stage of the tide as they went past Lockwoods Folly or Shallotte. So for the time being the only thing we can say is that between Beaufort and Little River, shallow draft boats can make it at some state of tide without problem. Marinas from Southport to Myrtle Beach are reporting that there is almost no boat movement. Beaufort Town Docks reports that most boats are going outside from Beaufort to points south.
