OK, it's mythbusting time!

Last October various Australian weather forecasters predicted that there would be 15 tropical cyclones in our waters during summer. That's five more, or an increase of 50%, than an average year. Their predictions were based upon the formation of the la nina weather phenomena that affected eastern Australia during the summer. During la nina years warmer than average water pools off the east coast of Australia providing conditions conducive to tropical cyclone creation.
