southward into the local Georgia waters tonight. The boundary will
stall tonight into the holiday weekend bringing waves of showers and

frontal boundary and move over the coastal waters on Friday. The
low will linger over the coastal waters this weekend potentially
bringing Small Craft Advisory conditions before lifting northward

monitoring this system to see if the low will become a tropical or
subtropical depression.
