Severe shoaling has been reported in the vicinity of Little River-Winyah Bay Daybeacon 22A (LLNR 33710.5) & Daybeacon 25 (LLNR 33735). A temporary Buoy 22A has been set in approximate position 33-44.5094N/078-51.9702W. Little River-Winyah Bay Daybeacon 22A has been temporarily changed from a non-lateral aid to an NW on pile (diamond shape, white day boards with an orange reflective boarder). The approximate width of the channel from the pier on the east side to TEMP Buoy 22A on the west side is roughly 60ft. The pier on the east side is not lit and the width of the channel with the extreme shoaling on the west side poses a serious hazard to navigation. Mariners are advised to use extreme caution while transiting the area.
