I think this is what you are talking about. I am also on the DD and concerned about this. Right now it only has the potential for tropical development. The dots on each computer model line represent where they think it will go in 12 hour increments. So the end of the lines are roughly 5 days out. A lot can happen in 5 days so its really no telling yet. If it keeps at the same rate as what the predictions say then it would be within range of CC in about a week, Port canaveral in 8+/- days.
Now if you look back at Fay, they thought it would head straight up the middle of FL all the way up into NC. Then they thought it would curve west in GA/SC. What it
has done is cross FL diagonally and is now looping back.
So there is no way to know if this will affect us at all. I'll for one be keeping an eye on it.
