Tropical Cyclone 13P Forms Northeast of Australia

A second tropical cyclone formed near the coast of Australia when a center of circulation developed in a cluster of thunderstorms northeast of Queensland.  At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone 13P was located at latitude 16.5°S and longitude 155.9°E which put it 385 miles east of Willis Island and about 800 miles north of Brisbane, Australia.  It was moving toward the south at 7 m.p.h.  The maximum sustained wind speed was 40 m.p.h. and there were gusts to 50 m.p.h.  The minimum surface pressure was 996 mb.

Tropical Cyclone 13P is near the western end of a subtropical ridge and moderately strong northerly winds are blowing over the top of the circulation, especially over the eastern half of it.  As a result, more thunderstorms are forming in the western half of the circulation.  The tropical cyclone is over Sea Surface Temperatures that are warm enough to support intensification.  The upper level northerly winds are enhancing outflow to the south of the circulation and so some intensification is possible.

The subtropical ridge is expected to steer Tropical Cyclone 13P in a generally southwesterly direction, which will move it toward the east coast of Australia.  A landfall near Gladstone could occur in 36 to 48 hours.
