FYI... a category 4 in this region of the world is a cyclone of approx 930-955mb with winds of 165-225 km/h (105-140 mph). This would equate to a maximum category 2 to a minimum category 4 in the Saffir-Simpson Scale.

Currently, Monty is a 125 mph cyclone. This is on the upper-end of category 3.

that you brought that out (I was about ready to dig out my copy of the Category definitions used by the Australians) since the Saffir-Simpson scale is really only applicable in the US though NHC applies it to the EPAC and ATL basin areas outside of CONUS as well.

This link show a listing of their Cyclone categories. On thing that stands is the fact they register the highest gusts instead of maximum sustained winds.

Is that scale the same as the ATCI scale?
