Caused by hurricanes, the rapid groetds a growth and sprawl in the houston area has created worse conditions for a storm like this. Its also created some insurmountable challenges in terms of trying to move people out of harms way and trying to rescue people when the effort to get them out of harms way is a failed effort. So were continuing to watch this story tonight. Were going to be getting a live report from houston in just a moment. Were also going to be speaking with an expert tonight who is an expert specifically on the question of what options houston has right now. What options texas has right now in the middle of the thing to cope with what has happened over the last four days and what is likely to continue to get worse over the next 48 hours. They have some very painful decision to make. And getting a sense of what options they have and what the consequences of the decisions might be at this point. Its very difficult stuff but were going to be covering that in detail tonight
