A Tropical Low formed west of Darwin, Australia on Wednesday night. At 10:00 p.m. EST on Wednesday the center of the Tropical Low was located at latitude 12.5°S and longitude 128.5°E which put it about 160 miles (255 km) west of Darwin, Australia. The Tropical Low was nearly stationary. The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1006 mb.

The circulation around a small low pressure system over the Timor Sea west of Darwin, Australia exhibited more organization on Wednesday night and the Australian Bureau of Meteorology designated the system as a Tropical Low. The strongest thunderstorms were occurring in bands northwest of the center of the circulation. There was also a band of thunderstorms in the southwestern part of the Tropical Low. Bands in the northeastern part of the circulation consisted primarily of showers and lower clouds.

The Tropical Low will be in an area where the steering winds are weak during the next 36 hours and it is forecast to remain nearly stationary. The Tropical Low will be in an environment somewhat favorable for intensification. The Tropical Low will be over water where the Sea Surface Temperatures are near 30˚C. It will be under the northern part of an upper level ridge centered over northern Australia. The ridge will produce easterly winds that will blow toward the top of the Tropical Low. Those winds will cause moderate vertical wind shear and the shear will inhibit intensification. The Tropical Low could gradually strengthen during the next 36 hours.

The Tropical Low is forecast to move toward Australia during the weekend. A Watch has been issued for the portion of the coast from Point Stuart to Kalumburu. The Watch includes Darwin, Wyndham, Wadeye and the Tiwi Islands.
