A large fire burning out of control in Victoria’s Grampians National Park has created a smoke plume so large that it can be seen clearly from space.

Persistent southeasterly winds flowing over Victoria on Wednesday have been fanning a fire in the Grampians National Park. These sustained winds have forced the fire to spread towards the northwest, while also carrying smoke close to 100 km ahead of the fire front.

The map below shows the modelled winds over western Vic on Wednesday afternoon, with the location of the fire indicated with the red icon near the middle of the image.
