A weak non-tropical low pressure area interacting with an upper-level trough has formed to the southeast of Myrtle Beach, South Carolina, and NHC has issued a Special Tropical Weather Outlook. At 19/12Z, Invest 93L was located at 32.6N 77.3W with sustained winds of 30kts and a central pressure of 1009mb.

The system is drifting to the southwest and upper south southwesterly windshear has displaced most of the convection to the north of the low pressure center. This southwesterly shear is expected to abate over the next couple of days, however the SSTs are a chilly 25C. There is a 50/50 chance for additional tropical or subtropical development.
