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 clouds/surface composites are created by combining information from two images. The Earths surface (land and oceans) is a static image from NASA's Blue Marble image set. The cloud cover, which is overlaid on top of this surface image, is derived from a greyscale infrared image (see Infrared Images), by removing the temperature range associated with the surface. While a clouds/surface composite gives a good indication of the current cloud cover, it should not be confused with a true visible image.
