Here's the maximum storm tide in a worst case scenario for Texas coast

"Ike has a good chance of becoming the most destructive hurricane in Texas history--though not the most powerful."

and latest IR loop of Ike

As crazy as that looks, it really needs to have the description with it:

Figure 2. The maximum storm tide (storm surge plus an adjustment for hitting at high tide) expected from a mid-strength (145 mph) Category 4 hurricane hitting anywhere along the coast of Texas at high tide. This so-called "MOM" (Maximum Of the Maximum Envelope Of Waters) is computed using NOAA's SLOSH storm surge model. The plot above IS NOT the expected storm tide everywhere along the coast from a hit by Hurricane Ike. The plot is the MAXIMUM high water for a worst-case scenario Category 4 hurricane moving at the worst possible angle at the worst possible forward speed. As such, this plot is the combination of SLOSH runs from over 50 different simulated hurricanes approaching the coast at different angles and different forward speeds. The maximums plotted here are only possible along a 20-mile stretch of the coast on the north side of Ike's eyewall. SLOSH model runs are advertised as being in error by plus or minus 20%.

This is the worst case scenario of 50 simulated hurricanes, and would only happen w/in 20 miles of the eye (not 100 miles of coastline).

The UofT at Austin has an excellent collection of Texas Topographic Maps. Also some maps of evacuation routes and the like.

The Dude started a current events thread over at peakoil.com as well: Hurricane Ike Impacts to Infrastructure. The Bryan Mound SPR site (226 mb) is only 15 ft above sea level, BP and Marathon's refineries at Texas City look to be even shallower - 8 ft? Topo map at UofT is dated 1932...these sites look likely to get a good soaking even if the eye is some distance off.
