As was just mentioned in the TX gov.'s news conference, the high that is helping to steer the hurricane more northward is anticipated to lose strength. Thus they expect the storm to at some point resume a more westward course. Lots of variables in play. It will go somewhere between Port O'Connor, TX and New Iberia, LA, and likely between the town of Matagorda and Lake Charles. Can't simply extrapolate based on a few hours movement, things are too dynamic.
A weakened high would allow it to go further east, not west.
About the only certainty right now is that a direct NO hit is impossible.
