The effects and duration of the track across Cuba will tell us what to expect from Isaac. If the track is short, then we'll be dealing with a stronger system entering the Straights of Florida. If the center lingers over Cuba, it will become more disrupted and weaker. Once we know when and where the center emerges from Cuba and over the Straights, we'll have a much better idea of what to expect in Florida/GoM. With the models trending slightly eastward again, no one should relax and discount Isaac's future as to how it will impact Florida. Isaac, by no means, is a Charley or Katrina, but being a very large system, it will impact a very large area as it moves along during the next few days. I've nearly completed my preparations, so needed or not, I'm prepared to weather a strong TS or minimal hurricane right here at my house.
