Tropical Low Forms Northeast of Queensland

A Tropical Low organized quickly northeast of Queensland over the Coral Sea on Thursday.  At 11:00 p.m. EDT on Thursday the center of the Tropical Low was located at latitude 16.1°S and longitude 151.4°E which put it about 370 miles (600 km) northeast of Townsville, Australia.  The Tropical Low as moving toward the south at 9 m.p.h. (15 km/h).  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 1005 mb.

The low level circulation of the Tropical Low organized quickly on Thursday.  Numerous bands of showers and thunderstorms formed and they began to wrap around a center of circulation.  The distribution of showers and thunderstorms was relatively symmetrical, although there are a few more storms in the eastern half of the circulation.  Storms closer to the center started to generate upper level divergence.

The Tropical Low is in an environment that is very favorable for intensification.  The low is over water where the Sea Surface Temperature is near 30°C.  The upper level winds are light and there is very little vertical wind shear.  The Tropical Low is likely to continue to organize quickly in the favorable environment and it will likely become a named tropical cyclone on Friday.  Once thunderstorms consolidate around the center of circulation, a period of rapid intensification may occur.

The Tropical Low is currently being steered to the south and that motion could continue for another 12 to 24 hours.  A strengthening subtropical ridge is forecast to turn the Tropical Low toward the west in about 24 hours.  On its anticipated track the Tropical Low could approach the coast of Queensland in about three days.
