Since all these are inevitable and the current flooding of Thailand and Cambodia be of any reference, then all of Malaysia should start to get ready for all these soon to be natural disaster. We should stock up on dry and canned food, bottled water, blankets and temporary bedding and all the logistic channel all these aids and rescue persons is distress. Prone areas flood relief centres should be made ready ahead of the natural disaster. Essential medicine should also be stocked up.

Of course, whatever sampans, dingy or small water-crafts which include recreational machines such as jetskis that would make any of these logistic operations smoothers should be made ready and available when they are needed to be deployed.

In short, brace for bad weather. God help us all.
