Thanks for your input Whitey. When it comes to squalls, earlier is far better than later. So many guys just waited too long and then their options vanish. It is a good thing to well secure on the beach before things hit too. Runaway kites can easily mess themselves up and occasionally folks downwind.
Here is the ikitesurf image you mentioned for Dunedin for 2.13.08. The first spike looks like a squall with the confused wind direction changes. Note the violent direction changes happened after the spike. There is no telling what a squall will do, mega-spike the winds, kill them, change direction or do little. You only know once it is on you. The second from the direction and spike change looks like the passage of a frontal boundary and squall line.
