Tropical Cyclone Mitchell hit the coast of Western Australia last week. It initially developed as a weak tropical low over the Northern Territory in early February, then tracked over Western Australia’s Kimberley region and eventually reached the Indian Ocean.

Fuelled by warm waters, Mitchell intensified into a tropical cyclone and moved south-west, hugging the coast of Western Australia and eventually deepened to a category three storm.
