It all depends on what happens with the wave that is approaching the Lesser Antilles. The good news is that the models have trended a bit further south with the system. The two main models bring it across Florida and into the Gulf of Mexico. They split after that. The GFS is further west and brings the system toward Texas and Louisiana. The European, which trends to be more reliable, turns it toward Mississippi and Alabama and then lifts it northward. This would mean rain for Myrtle Beach, especially in the Wednesday / Thursday time frame. The ensembles, basically each model run with slightly different initial conditions, still have a spread though. It is still a week out though, so hope for the best.
