Invest 90S looks as though it might be a significant Tropical Cyclone according to the GFS Ensemble while not every track has the same depth of the low a lot have it getting bellow 990hPa and a couple have it getting bellow 950hPa which is the territory of Mean Sea Level Pressure you find in storms of Category 4 (Saffir Simpson Hurricane Wind Scale) though the winds really depend on the pressure surrounding the system too, high MSLP surrounding a Tropical Cyclone the higher the winds

Invest 96S on the other hand doesn't look like it will have significant development anytime soon but worth watching over the next few days as new information could change how the models play out and may point to more development than is currently showing

Invest 91P is another system which by what the GFS Ensemble is showing as the potential to become a significant Tropical Cyclone at the moment it is unlikely to cross into the Australian Basin instead head East, Quite a few tracks have it reaching sub 990 and 980 hPa so not as deep as what 90S is showing in the models but still pressures you might see in a Hurricane/Typhoon forced storm (so Category 3 Severe Tropical Cyclone on the local scale which is the Australian Tropical Cyclone Scale)
