Tropical Cyclone 10S (Dominic) - January 26th, 2009

Tropical Cyclone 10S (Dominic) is now located approximately 115 nautical miles northeast of Learmonth, Australia. It has moved southwestward at 6 knots over the past 6 hours.

A weather radar loop from Dampier, Australia show the low level circulation center has slowed down and convective bands wrapping into it have tightened slightly.

It is showing a well-definied center. The maximum significant wind speed has increased to 40 knots, with gusts up to 50 knots. Maximum significant wave height is still 12 feet.

The system remains in an environment favorable for continued development with low vertical wind shear and warm sea surface temperatures.

Dominic is tracking along the northwest periphery of a low to mid level subtropical ridge.

However, at TAU 12, a mid-latitude trough will weaken the steering ridge, causing the cyclone to slow further then recurve southeastward towards land and dissipate.
