A cloud band with embedded thunderstorms extends across southern and central
districts of Western Australia ahead of a strong cold front approaching the
southwest coast. This front connects to a low pressure system located further to
the southwest. Patchy high to middle level cloud is streaming ahead of the cold
front across the Bight.

Another cold front is approaching Tasmania with high level cloud affecting
Tasmania. Onshore winds and a low pressure trough are causing isolated
thunderstorms along the southern Queensland and northern NSW coasts.

Mostly clear skies over the remainder of Australia.

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.
