The monsoon trough is active across northern Australia and is resulting in
extensive cloud with rain areas and embedded thunderstorms. A tropical low is
located within this trough over the Top End of the Northern Territory.

Another surface trough is responsible for the cloud and thunderstorm activity
over the Coral Sea. Middle and high level cloud extends further south over
central districts of Queensland.

A patchy cloud band with thunderstorms associated with an upper level trough can
be seen stretching from Western Australia, across central South Australia,
through New South Wales and into the Tasman Sea.

High level cloud ahead of an approaching cold front can be seen flowing over
Tasmania and into the Tasman Sea.

The remainder of Australia is mostly clear.

About these Images : The Bureau provides these false colour infrared images that use the Zehr colour enhancement, which was developed by Ray Zehr from the US National Oceanic and Atmospheric Administration (NOAA). This enhancement only applies temperature colour ranges to the cold end of the scale, which highlights very deep convection that is generally associated with tropical cyclones and thunderstorms. Hence, this type of image can be useful in tracking the movement of tropical cyclones.
