A NASA satellite captured an unusual smoke column over a bushfire in Western Australia December 8 southwest of Walpole. Apparently there was little wind to disperse the smoke, causing it to build up in a round shape, as seen overhead. This was very different from the smoke pattern we showed you on December 7 created by another fire in Western Australia.
The red dots are heat detected by the visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite.

A large bushfire in Western Australia forced authorities to close a major highway resulting in hundreds of long-haul truckers and tourists being stuck on the road for hours. Some of them were stranded between roadblocks that were 170 kilometers (105 miles) apart.
Wednesday morning the Eyre Highway across the Nullarbor was closed between Caiguna Roadhouse and Madura. By evening it was open again.
There were two large fires south of the highway that were being pushed by the wind toward the road.
The fire started from lightning four days ago 20 kilometres (12 miles) south of Cocklebiddy.
Below is a time-lapse video of satellite photos of smoke from fires in the area.
This time-lapse video of the pyrocumulus cloud over the Sedgerly Fire in Queensland, Australia is fascinating. According to the description by the Bushfire Convective Plume Experiment it shows a thunderstorm initiated by the fire. If you look closely you will see rain and lightning.
