In other video that is searchable from the links but has not visual info on the disaster it is seen a true watershed falling on the site (people was throwing themselves over the counter of fair kiosks to get undercover from the water). Even if it is clear that some statistical failures are ever to occur on variegate reasons, it also can be that we are having more turbulent weather than we are accustomed to in our technical memory.
For example, in the town I live it seems the storms have severely receded the last years where in other places are getting worse.
The bigger turbulence seems to come from the need to accommodate bigger gradients of temperature resorucing to the finally more efficient way of getting away with the dissipation of the cinetic energy in turbulent way; and I think there is already at least one book out there on acclimation of structures to climate change, if I find what will post.
