 :Actually, I've seen some Filipino news and/or videos about weather and saying about the boat sinking due to the storm. A site I just looked at a few minutes ago, it says that the driver in the boat was having trouble to steer the wheel and the date was on September 13. I remembered that the day when it sink, the outflow of Kalmaegi combined with the southwest monsoon was in the area. Or Kalmaegi's southern outflow reached to southern Visayas since the boat sink there.   "
