@edgarblythe,
Edgar, mac, anyone else on the Texas coast(?)...
It's still only Wednesday but the folks that I read/listen to on these things are comparing Ike to Carla (1961) in terms of potential strength, storm surge, and impact away from the center. "Strong 3 - weak 4" is the current estimate at landfall with hurricane force winds reaching out 50 miles north and south from the center and major storm surge (20 -25 ft) just north of the eye wall.
The biggest problem in predicting the path is that he's only moving at 8mph. Moving so slowly means 1) that he has plenty of time to get stronger, and 2) there's plenty of time for upper level lows and highs from the north to impact his direction.
I'm sure you're watching local forecasters closely but, if you haven't already, do start thinking of making contingency plans if there's any further shift to the north.
