Not long after being declared tropical, early signs of an extratropical transition appeared. Cold air began to enter the storm on the west side and forecast models showed Laura becoming extratropical the next morning and non-tropical later the next day. Overnight, convection associated with Laura began to diminish and lose tropical characteristics, but still retained its status. Early on October 1, the extratropical transition was fully apparent. Laura remained tropical but the cloud pattern was becoming frontal and there was little convection around the center of the system. Laura later degenerated into a post-tropical cyclone, a term that had been previously used by the Canadian Hurricane Centre to describe a storm that has lost tropical characteristics, but is not subtropical or extratropical. The transition was forecasted to be complete by the end of the day.
