I visited with my college roommate and her husband today. Her family in Katy (most western part of Houston) was fine, intermitent power issues but otherwise just like a big old thunderstorm. She said her friend is getting married in two weeks and now doesn't know what will happen. The restuarant they were having the bridal luncheon at burnt down, the same place was supposed to make the wedding favors. Her reception venue and church may be flooded due to the location but her family is okay.
My friend's husband said his parents were on a scheduled trip to Kansas. His brother and sister were home in Cleveland (NE Houston) and were without power and lost many trees. They wished after that they had left. They do have generators but expect to be without power for 2 weeks. But they are okay and so are his nieces and nephews. 
Unfortunately it looks like there will be a high death toll but I am hoping I am VERY wrong about that. Just a lot people stayed and the flooding. Keep praying for all who did not evacuate and those who will head back to clean up.
