Erika Degenerates into Depression

As of 5PM EDT the National Hurricane Center has downgraded Erika to a tropical depression. This comes as no surprise given the high shear and dry air that has been talked about the past few days. Upper air conditions are expected to remain unfavorable across the Caribbean. Furthermore, the weak center will have to contend with mountainous Hispaniola. Erika will likely degenerate into an open wave. Nevertheless, Erika's remnant will continue to be monitored as it heads toward the Bahamas.

Elsewhere, model guidance suggests that 1-2 tropical cyclones may form from tropical waves about to exit the coast of Africa. The models also depict a vigorous trough in the central Atlantic. This trough would quickly recurve any tropical systems that quickly strengthen in the east Atlantic.
