Floods in Samui happen every year ath this time - same thing happened at the same time last year, airport closed a bit or water on the roads. The main disaster is that no one has thought of putting in adequate drainage and loads of trees have been felled on hillsides to make way for luxury housing which leads water to pour down off the hills when it rains.
