A tropical wave moved through the northeastern Caribbean on October 10, with a large area of associated thunderstorms. The wave interacted with a stalled frontal boundary, developing a broad circulation by October 13 to the northeast of the Bahamas. A day later, the system developed into a subtropical storm – its classification was because the system was co-located with a trough. There was another area of convection along the front northeast of the subtropical storm, which accelerated northeastward. Meanwhile, the subtropical storm turned westward. It had a small circulation with thunderstorms sheared north of the center, which gradually became more organized. On October 17, an approaching front turned the storm northward and later northeastward. On the same day, the subtropical storm transitioned into a tropical cyclone. On the next day, the storm attained peak winds of , before it transitioned into an extratropical cyclone. The storm later moved over Atlantic Canada and was ultimately absorbed by the cold front on October 19.
