Well it is up to you, but I would not even THINK of going there this weekend.
Many areas are still flooded, many areas do not have drinking water, many areas do not have electricity.
Many local evenbts are being cancelled.
The flood waters are not "clean" and are river water mixed with sewage, oil and dirt from factories and so on.
Do you really want to go for a break in that ?
One couple who went to the area LAST weekend for a Blues festival are still trapped there.
The weather report for the next few days shows rain
