My daughter's home in Houston is under water now. Fortunately she evacuated her family (2 adults, 2 kids, 2 dogs) to Dallas Friday and they have a place to stay for at least the next week. She works at MD Anderson Cancer Center and her building already had water into the second floor, so they can't see outpatients or take in anyone for surgeries.
With the worst of the rain still to come, this is an epic disaster for those in the area. Everyone should look for ways to help any way they can - Red Cross, etc.
