Flooding in Davao

Everytime I call my family in Davao,they always said it's raining a lot and it's everyday.Though there was already an improvement on the drainage system in Davao but still the city experienced flooding.My father said that,there are some houses were drifted by the strong current of river and along the sea shores.Fortunately in our place,it didn't flood.Hope this heavy rain will stop for a while.
