Según comentan posiblemente esta tarde (noche en España) tengamos la DT1 del EPAC en el 2017. Lo modelos de forma general ven movimiento al oeste en 48-72 y después un giro brusco al Norte o Noreste y bastantes papeletas de que llegue incluso a ser Huracán antes de impactar con centroamerica.
Mirando la imagen satélital diría que ya es DT, y cuidado no sea tormenta tropical.

Adrián pierde fuelle rápidamente pese a adentrarse en aguas cálidas y con poca cizalladura. Supongo que el aire seco le estará dando problemas. Ahora mismo casi no presenta convección.
Según el NHC se espera que acabe disipándose. Ahora mismo posee 25kt - 1008hPa de intensidad.
Saludos.
