Cyclone Trevor could intensify to a category five storm by the weekend, the Bureau of Meteorology said.

The storm, currently sitting in the Gulf of Carpentaria, is expected to become category three by Thursday afternoon, and could become a category five cyclone in the next two to three days.

Authorities are evacuating residents in Gulf communities with the cyclone’s core expected to cross the south western coast of the Gulf of Carpentaria, between Groote Eylandt and Borrooloola, on Saturday.
