Tornadoes in the Philippines?

There has been a lot of changes in the Philippine weather system in the past ten years. One of the most alarming changes to hit the country aside from "more than the usual" amount of rain, are the tornadoes forming all over the country. From water spouts to really dangerous tornadoes, they are now in the country and it is quite a concern to most localities since it is something that most Filipinos aren't prepared of. It is a challenge because having your own underground shelters is not a normal part of a house in this tropical country.

Should we be worried about this present state of our weather?
