Further to my earlier post, if you look at the satellite photo you can see a few blobs in the Indian Ocean that have appeared. And also the moisture and cloud just North of Darwin.
Well its no longer a theory, it has begun. This moisture is heading South and will get dragged down in front of the system, by this time tomorrow night i expect a decent cloud band to have formed on the front. Will see what it looks like in 24 hours.
To see it more clearly click this link and watch the moisture on the move, it wont result in much rainfall due to the high winds but the shift is on.
