I'd call it overtopping from that description - the current wind direction, from the WSW, is pusing water from the Gulf up into Ponchatrain and causing modest surge. However, recall that a wall used to be in place at the former breach point - and that wall is no longer in place. So it wouldn't take much of a rise to overtop the levee at that point.
So the key question is, will it remain overtopping? Or will the water eat down into the repairs and re-open the breach?
And then there's that little problem of 5 inches of rain when the city pumps are not fully back on line yet...
Looks like it's well on the way to becoming a breach.
