A Tropical Low formed over the Timor Sea northwest of Darwin Australia on Saturday. At 8:00 a.m. EDT on Saturday the center of the Tropical Low was located at latitude 10.3°S and longitude 129.0°E which put it about 105 miles (165 km) northwest of Darwin, Australia. The Tropical Low was moving toward the southwest at 6 m.p.h. (9 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 996 mb.

A Tropical Cyclone Watch was in effect for the portion of the coast of Western Australia from Kalumburu to Cockatoo Island.

A low pressure system over the Timor Sea northwest of Darwin, Australia strengthened on Saturday morning and the Australian Bureau of Meteorology designated the system as a Tropical Low. The distribution of thunderstorms around the Tropical Low was asymmetrical. Most thunderstorms were occurring in bands in the western half of the circulation. Bands in the eastern side of the Tropical Low consisted primarily of showers and lower clouds. The Tropical Low was moving under the northern part of an upper level ridge over northern Australia. The ridge was producing easterly winds that were blowing toward the top of the Tropical Low. Those winds were causing moderate vertical wind shear and the wind shear was causing the asymmetrical distribution of thunderstorms. Storms near the center of circulation generated upper level divergence that pumped mass away to the west of the tropical low.

The Tropical Low will move through an environment that will be somewhat favorable for intensification during the next 36 hours. The Tropical Low will move over water where the Sea Surface Temperatures are near 31˚C. However, the upper level ridge over northern Australia will continue to cause moderate vertical wind shear. The Tropical Low is likely to intensify gradually during the next 36 hours. It could become a named tropical cyclone during that time.

The Tropical Low will move around the northwest part of a high pressure system over western Australia. The high pressure system will steer the Tropical Low toward the southwest during the next 36 hours. On its anticipated track, the Tropical Low will move parallel to the coast of Western Australia during the weekend.
