I would be very wary of the models posted on public sites, for several reasons. They were initialized using data less recent than what is out now, for one, but the biggest reason is because none of the models forecast the huge slow down/near-stall that Ike is doing currently. This could have HUGE implications on the track and landfall, as slowing down will give the trough enough time to pull Ike more northward and closer to us. It's going to be bad, even with a landfall near Matagorda -- but one closer to Freeport would be disastrous.
Look at how little Ike is moving:

Many decisions are being made today... Be safe, everyone in Ike's path!
