After maintaining peak intensity for about 24 hours, Kyle began weakening on September 27 as increased upper-level shear restricted outflow and distorted the convection envelop; drier air also contributed to the weakening. On September 28, after turning west-northwestward, the hurricane weakened to tropical storm status, and by the next day the center had become exposed from the deep convection. A trough passing to its north and a developing ridge to its west left the storm nearly stationary for several days. The weakening rate of Kyle was temporarily halted when thunderstorms re-developed on September 29 and again early the next day, though late on September 30 the storm weakened to tropical depression status. The circulation had become elongated from northeast to southwest. The northeast portion became associated with the approaching frontal zone, and was briefly monitored for signs of development. However, the southwestern portion re-developed convection and became the dominant circulation.
