By the morning of the October17, Roslyn had developed into a hurricane south of Acapulco. A vigorous upper trough was deepening offshore Baja California, and Roslyn began to re-curve within a few hundred miles of Manzanillo. The system struck Mazatlan as a marginal hurricane on October20. The low-level center rapidly dissipated, although a frontal low developed in the western Gulf of Mexico, which moved over southeastern Texas and later through the Mississippi Valley. The original upper-level circulation maintained its northeast movement, bringing rainfall to the Southeastern United States.
