Rain Pours

Yesterday, June 5,2008, Davao City experienced a very heavy rain that resulted to flood on the streets of the city. Though it was just like an hour of a very heavy rain, still it flooded. I was wondering why it happened that usually few years ago Davao City, never experienced this kind of event.

And today, It's been raining since past 7:00 in the evening and time check, it's 1:10 am in the morning, still on its heavy rain status. What will happen to Davao city tomorrow after this rain?
