Interesting....anyone wanna reply?

Mr. Watkins brought up an interesting point. Here is what he had to say...
"Ivan is getting squeezed.

As mentinoed in the other post on this topic...the northerly flow piling up to the north of Ivan is what halted the northward movement. It looks...to my tired untrained eyes...that the ridging is starting to pile up to the west of the hurricane as well:

This sinking motion observed there is spilling over the outflow and not appears to be piling up to the west . This may not last very long and could very well come to an end soon...but this blocking would explain why the hurricane has slowed way down.

If the mid/upper system (and there is evidence that it is not strictly an upper system...look at the convection associated with it) does not lift out or weaken it will start to clear out some of the ridging to the north of the hurricane and allow it to spring north some.

Not saying it will cause this to head for Miami or anything...because I'm not...but I am trying to explain why the hurricane has slowed and jogged a little to the north today.

These features are going to be very interesting to watch over the coming hours... "

Why not just bump up Mr. Watkins post rather then create a new one?

bad news. outflow is starting to look much better. Yesterday even during the most intense strengthening some shear on the NE side prevented a good outflow, I think from the sat loop, that is definitely over.

Agreed, I think Ivan may be about ready to head north and speed up considerably in the next 3-5 hours, closer to 3.

North or Northeast or both? Here in Central Fla we're watching carefully
