sentences:  After it had been named, Rosie weakened into a category one tropical cyclone with the low level circulation centre became devoid of convection as it moved towards the south-southeast towards Christmas Island.However convection redeveloped over the system later that day, but failed to become sustained or organized, as a result TCWC Perth reported early on 23 April, that Rosie had weakened into a tropical low despite it having 10-min windspeeds of 65 km/h (40 mph).During that day convection and gale-force winds eventually became confined to the south-east quadrant of the cyclone before the JTWC and TCWC Perth issued their final advisories on Rosie during 24 April as all convection surrounding the system had weakened and dissipated.
