Stronger Hurricanes and how they affect their environment?

[Dmetal81]

Quick question. Since Charlie looks like it may be a bit more intense as it makes that turn then originally forecasted, how much can we expect this to effect its turn and how it feels the effects of the trough. I know that major hurricanes at times can affect the upper air environment and steering currents around them, but Im not exactly sure in this situation how that would work. Any thoughts?

Depends..

Larger storms tend to affect their environment more...but for a storm the size of Charley, and with the front approaching, it would probably have to have a minimum pressure of at least 910-920 mb.

The ones that "create their own environment" tend to either A) Wobble/Move Erratically or B) Shift westward.

A high pressure dome often builds over strong hurricanes. If you look at the water vapor imagery you can see this starting to happen with Charley. There is an expanding boundary area near 27N 87W. The trough looks quite strong but this might delay a turn to the north by a few hours.

It won't be a factor at all..that only works with large, intense storms and very weak steering currents.

Air Force -

i.e. with Isabel when it was a Category 5 - but even so it still was susceptible to steering currents eventually as it weakened.
