 Later that day, the FMS named the depression Amos, after the system had developed into a Category 1 tropical cyclone on the Australian tropical cyclone intensity scale.However, further development of the system at this time was restricted by a trough of low pressure to the northeast of the system, which was causing subsidence over the systems north-eastern quadrant.Amos subsequently slowed down later that day and became nearly stationary, as a near-equatorial ridge of high pressure became the primary steering mechanism.
