There is a fairly strong disturbance to the immediate north of Michael. I believe that this will get Michael up and moving, but the movement will likely end up going west, towards Leslie.
It seems that strong cyclones will try to orbit each other, and this is referred to as the Fujiwhara Rule. In this rule, two strong cyclone vorticies will attempt to orbit each other, and this may very well happen to Michael and Leslie. As a weakening Michael moves towards Leslie, Leslie ought to try and also shift towards Michael. Whether this happens remains to be seen, but will be something to watch for.
However, I am seeing a depression in what appears to be the center of Leslie. Whether this is the forming of an eye or not, it is something I believe should be eyed closely over the next several hours, as this could indicate strengthening.
