Upper level ridge trying to form off east coast of FLA????

[Stratosphere747]

I would think Dennis would need to slow down, before being impacted that much by the High?

It seems like the forecast models are having trouble dealing with the strength and/or weakness of this high pressure system. IMO this is the key factor in where Dennis will or will not go.

Is it a myth or is it fact that the really strong canes (and Dennis may or may not qualify, but for July he does) tend to "create their own environment?"

I believe that this is true.

I think it's true to an extent...and in fact I asked that very question not long ago on my local weather board.....tis a shame I can't remember what the answer was...lol
I don't think however that it can plow through a ridge no matter how strong it is....it will still have to ride around it.

I would think that this would depend on the strength of the ridge.

Yes, they can create their own environments, e.g. Gilbert in 1988. Because hurricanes are nature's way of transporting heat out of the Caribbean to the north, stronger hurricanes will tend to gravitate more towards the poles.

You can see the ridge circulation in the water vapor loop.
So far Dennis has not responded much to the ridge but i'm guessing the strongest part of the ridge is still north of Cuba.
In the mid gulf it actually looks like the ridge is beginning to expand northwest a little but its too early to tell.
Dennis could actually pump up the ridge as large storms often do and that could lessen the shear that was forecast before landfall on the northern gulf coast.
