Water leaks in at floor level when raining

During a hard rain water leaks into room at floor level. I've had the grout line cleaned and resealed. During a recent rain, I observed the area where the water is entering from and I could hear water falling inside wall before appearing on floor. It doesn't appear to be the grout as I thought. Could it be the caulking/sealant around the outer window frame or what?
