Not yet, Ivan is still south of Jamaica and is not going to sneak up on anybody. It's still way to soon to tell where this storm is going to go. Pretty much everyone from Florida to Texas is nervous, because it is further south than the last one and that means that there are a lot more places that can get hit.
I am not sure exactly when the squadrons in P-Cola will put their Hurricane Evacuation plan into action, but I know that the HT's only leave the area if it is a catagory 4 or 5 storm. If it is a 3 or lower, they just put all the 57's in hangars at South Field or Saufley.
The Keys may be jumping the gun just a bit.
