Exactly it... the analysis of what would have happened to Houston had Rita hit, specifically in the ship channel, is exceedingly frightening.

Local hurricane experts agree that a violent storm surge in the channel of at least 26 feet—a reasonable estimate for a category 4 storm that hits Galveston directly—would initially inundate densely populated, low-lying communities on the western half of Galveston Bay. Debris from those communities would then combine with thousands of shipping containers in the area, forming a destructive wall of steel and wood that would slam into thousands of chemical and crude oil storage tanks. Many tanks would be broken open by the battering ram of debris, while others would be ripped from their foundations by the water, releasing their deadly contents. A detailed inventory of hazardous chemicals around the Ship Channel remains difficult to come by, thanks to a Texas law that restricts public disclosure of information that could be utilized by terrorists. However, a 2016 Houston Chronicle investigation of the area’s dangerous chemicals revealed that communities near the Ship Channel live in close proximity to toxic substances, such as silane gas, methyl mercaptan, hydrofluoric acid, sodium sulfide, and ammonia. On at least three occasions, the investigation found, those substances have been released, killing workers and endangering nearby residents. The paper has also catalogued more than one hundred toxic releases during Hurricane Harvey alone, most of them from Houston’s petrochemical corridor.
