Technically, this is not classified as a cyclone but it is one for all intents and purposes. It's called an 'east coast low' which forms in winter off of the mid-east coast of Australia then usually travels south. It's rotating around a core with a 995 barometric reading. There was one a couple of weeks ago now we have another. The first caused erosion due to monstrous surf that left a few multi-million dollar 'absolute beach-frontage' houses teetering over the edge of collapsed sand banks. This one is causing flooding around Sydney with the likelihood of more erosion events tomorrow.
