Last year, Bangkok was severely flooded due to a run-off from up north. Floods continued for several months. This year the city is going under due to some severe storms. The problem is that the drainage system is having trouble in dealing with so much rain in a short period of time. This means that some areas of Bangkok will flood in less than 20 minutes. Once the rain stops it will then take about 2-3 hours for water to recede. Luckily for Bangkok, it doesn’t usually rain continuously day and night. Southern Thailand gets the real monsoon rains.
Before you get the impression that the whole of Bangkok is under water, let me say that just as many places around the city don’t flood at all. On the stretch of Sukumwit Road near my house, we are getting at the most an inch or so of rain on the road during the storms. It then drains quickly once it has stopped raining. In my book, an inch of rain on the road is hardly a flood. The Thai police have now come out with a list identifying 21 flood hotspots around Bangkok . These roads are prone to sudden flooding. With more big storms forecasted, you should be aware that there are more floods ahead.
