Ike is moving along as expected, but the longer term looks more uncertain. It completed its long NW run and has now turned West. The storm is in the process of turning WSW for a while, and then is projected to return to a generally westward path.
Ike is currently located roughly 450 miles north of the Leeward Islands and 500 miles NE of Puerto Rico, and is a Category 3 hurricane with maximum sustained winds of 120 MPH.
Ike is a relatively small storm geographically. The main part of the storm is less than 200 miles in diameter, and hurricane-force winds extend out only 30 miles on either side of the eye. Don't get lulled to sleep by these numbers because small geographic size is a good news/bad news proposition. The good news is the worst effects of a small storm don't extend very far; the bad news is that small, compact storms are usually more intense than widespread storms.
Ike is being weakened by some wind shear right now, and that will continue for some time. The storm is expected to weaken to a Cat 2 storm later today and remain a Cat 2 until Sunday. On Sunday, nowever, strengthening is expected to occur as the storm moves into the southern Bahamas, and it should return to Cat 3.
Sunday AM is 48 hours out, and the models are in general agreement that the storm will be somewhere in the southern Bahamas then. What happens after that is anybody's guess at this point.
The official forecast track shows the storm moving between the Bahamas and Cuba, striking the middle part of the Florida Keys Tuesday night, and being in the general area of Naples on Florida's SW coast on Wednesday. IF that occurs (and it is not at all clear at this point), Ike will probably strengthen to a Category 4 storm again prior to hitting the Keys.
However, two things are going on. One is that the whole package of models has moved significantly southward over the last 24 hours. Where we once hoped Ike would recurve out into the North Atlantic, we're now hoping it will stay south. That is a big change.
The other change is that further out than 48 hours, the models basically split into two groups, with one showing recurvature and the other taking Ike SW into Cuba. IF that happens, Ike will likely travel right down the spine of Cuba and will be greatly weakened by the mountains there.
Predicting hurricanes more than 3 days out is always difficult. When the models seperate like these have, it is really seriously unclear where the thing will be 4 days from now.
I know that doesn't help those of you traveling soon, but that's just the way it is. Bottom line: the changes in projected path and models have helped the early part of your trips.
Beyond that, it is too early to tell, and the path could change radically by tomorrow morning. The hurricane is a LONG way from Florida (1,200+ miles) and even a slight change in direction or duration of movement in a particular direction could move the landfall hundreds of miles.
