Tornado hits Makati during typhoon Frank

When Frank continue slashes in the Philippines, there was a report an tornado appeared somewhere in Makati. The video were cached by group of friends using there cellphone cameras during they having a party in the hotel. The sky became dark they thought just a rain but it’s not an tornado. As we know tornado is the most powerful storm on earth. It is often cases happen in the country during typhoon. I’m not sure it is a part of global warming or just only happens.
