As were have now reached the peak of the rainy season in Thailand, its probably a good idea to remind people again of the dangers of swimming in rivers and at waterfalls. Even on days when there hasn’t been any rain it’s possible to have flash floods. Don’t rely on warning signs put up park rangers. Look for your own signs. The most common warning that a flash flood is imminent is when the water suddenly turns a muddy brown. If you see that, get out of the water quickly. Don’t be fooled by the calm water or shallow depth. Many tourists have been swept to their deaths during flash floods at waterfalls. Don’t become a statistic.
