. The low did not move as it developed and became Tropical Cyclone Willy in the same area. Willy moved slowly west-southwest, roughly parallel to the Australian coast, strengthening steadily in the favourable environment. It reached its peak with 140 km/h winds on 11 March when it was 550 km northwest of Onslow. Cyclone Willy then turned to the southwest and maintained its strength for a day before it began to weaken. The storm turned to the west and weakened into a remnant low on 14 March. The remnant continued to drift west away from Australia before dissipating a few days later. Oil production in the

Tropical Low 11U

During 12 April a tropical low developed within the northern Arafura Sea. Over the next couple of days the system moved eastwards, with deep atmospheric convection developing over the western quadrants by 15 April. By this time the system was located about to the southwest of

and was producing gales and rough seas around Papua New Guinea. The system subsequently approached and interacted with south-eastern Papua New Guinea, before it moved into an area of increasing vertical wind shear and started weakening. The system was last formally noted during that day before it dissipated a few days later.
