I think the airport is only part of the problem.
When you leave the airport during the rains it is absolutely dire.Everywhere is flooded.
I once was on a flight to Manila during a storm. The airport was hit by lightning causing power failure so emergency generators were fired up.These were located in underground bunkers.Then, the water filled the bunkers,submerged and killed the generators.
Main power came back on later and we landed.Not a nice place.
