Tropical cyclone Bobby formed on 18 February north of the Pilbara coast and took a general southwest track remaining sufficiently offshore not to seriously impact the coast. Bobby peaked in intensity on 21 February northwest of Northwest Cape then gradually weakened, dissipating on 23 February.
Although there were financial losses to industry, there was no known impact to coastal communities. Bobby was the 14th cyclone for the season of 1983-84.
