 After maintaining its peak intensity for about 24 hours, Kyle began weakening on September 27 as increased upper-level shear restricted outflow and distorted the convection envelope; 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 devoid of deep convection.A trough passing to its north and a developing ridge to its west left the storm nearly stationary for several days.
