The flash flood triggered by Sendong is worse than that of Ondoy because it happened in total darkness. The flash flood happened between 2 am to 5 am when everybody was asleep. Most didn't have a chance to get up from bed when the water came rushing. Even those that were able to get out of their beds and houses didn't have a chance to go to safety. You can just imagine wading out in muddy water in total darkness not knowing which direction to go. From my experience during Ondoy, you have to go up to to a higher ground or climb a tree in ten to fifteen minutes( or even less)or you will drown. That is how fast the water rises during a flash flood. But how do you that in total darkness?
