No tropical development has been observed this morning and none is likely for at least the next 48 hours.

Once again, the Tropical Atlantic remains quiet as El Nino conditions are already dominating much of the Atlantic. Strong westerly to southwesterly shear remain over the Caribbean to the coast of Africa, which is inhibiting any disturbance from developing.
