one of the problems is that the powers that be (in Frankfurt or London or wherever) decided that the ITCZ should be removed from the SigWx charts
.
You now have to rely on knowledge, or look at the forecast winds on your Plog to see where they shift, or look at the CB forecasts to, at best, guess where the ITCZ may lie on a given day.
If anyone anywhere does not believe that the ITCZ is 'significant weather' they need flying through repeatedly it until they submit as a screaming crying wreck, the numpties.
