That area of deep layered moisture is part of the wave axis located along 10N 31W:
Atlantic Tropical Weather Discussion 8:05PM ET:
TROPICAL WAVE EXTENDS FROM 10N31W TO 2N35W MOVING W 15-20 KT.
I did the distance conversion from the ECMWF model, and the distance from the wave's current location and where the ECMWF first initializes the low at 120 hours is 3,321 miles. Divide that by the number of hours and this wave axis would need to travel at 28 mph (24kt). This wave has been traveling at a general 15 kt the past 3 days. This is the wave the NOGAPS is showing weak development of, the CMC shows weak development of both waves, bringing the wave currently located at 11N 47W over portions of SA and the Caribbean (the ECMWF also appears to bring the wave at 11N 47W over portions SA before developing in the Caribbean).
