This month, Cyclone Raquel became the first July cyclone in Australia's eastern region since the satellite era began in the early 1970s.
Jess Carey, a spokesman from the Bureau of Meteorology's Queensland office, said there was only about a one in five chance that the low over the islands would develop into a cyclone.
Conditions were not yet conducive for the low to form into a cyclone-strength storm but they might be “enhanced” over the weekend or early next week, Carey said.
