As of 9:30 AM, the axis of Tropical Wave 08 remains along 56/57W, moving west at 10-15 knots (18.5 – 28 KM/H). Moisture ahead of the wave is beginning to move across T&T, fuelling isolated showers and increased cloudiness.

Presently, neutral low-level convergence and upper-level divergence remain across T&T, with moderate to strong wind shear (20-30 knots), keeping these showers brief. The atmosphere is moderately moist as of the 8:00 AM atmospheric sounding, with a very marginally unstable atmosphere, though instability is forecast to increase through the day.
