Attack of the Cumulonimbus clouds in Cavite

monster clouds
Spotted this gigantic cumulonimbus clouds formation in Cavite, we saw this while we were on the road to Manila. Awesome sight and I think its our first time to see this cloud formation here, and then after a few days, Manila experienced a smog attack and many people thought that it was some kind of fog, and after that they learned from the news on tv that the fog is a toxic fog from our pollutants such as factories and vehicles.
