The above central Diagramhe shows the position of Category 5 cyclone Yasi, at around 4AM on Thursday morning February 3.
The cyclone moved from there farther inland on a WSW course and weakended to a Category 2. But (as I write this) damaging effects may be sustained in places as far as Mt.Isa and Camoweal 1000-1200km from the coast.   I myself am well out off the danger zone at the Sunshine Coast in SE Queensland, as shown by the lower red dot on above left picture. Darwin, also out off danger is located at the upper red dot.
