Perhaps what makes Irma even more striking is the fact that it (currently) is a Category Five storm headed straight for a major city (Miami). From the Wikipedia page:
"Cataclysmic damage will occur
Category 5 is the highest category of the Saffir–Simpson scale. These storms cause complete roof failure on many residences and industrial buildings, and some complete building failures with small utility buildings blown over or away. Collapse of many wide-span roofs and walls, especially those with no interior supports, is common. Very heavy and irreparable damage to many wood frame structures and total destruction to mobile/manufactured homes is prevalent. Only a few types of structures are capable of surviving intact, and only if located at least 3 to 5 miles (5 to 8 km) inland. They include office, condominium and apartment buildings and hotels that are of solid concrete or steel frame construction, public multi-story concrete parking garages, and residences that are made of either reinforced brick or concrete/cement block and have hipped roofs with slopes of no less than 35 degrees from horizontal and no overhangs of any kind, and if the windows are either made of hurricane-resistant safety glass or covered with shutters. Unless all of these requirements are met, the absolute destruction of a structure is certain.
The storm's flooding causes major damage to the lower floors of all structures near the shoreline, and many coastal structures can be completely flattened or washed away by the storm surge. Virtually all trees are uprooted or snapped and some may be debarked, isolating most affected communities. Massive evacuation of residential areas may be required if the hurricane threatens populated areas. Total and extremely long-lived power outages and water losses are to be expected, possibly for up to several months."
Note the rather ominous phrase "the absolute destruction of a structure is certain" and "Total and extremely long-lived power outages and water losses are to be expected, possibly for up to several months".
More to the immediate point, I have been reading about the evacuations. In this case - unlike Harvey and Houston - they were called for before the Hurricane arrived. The result? Similar to the post-Harvey effect: gasoline shortages, water shortages, stores sold out of every sort of thing. And this is before the storm has even arrived.
The highways are now choked, slowed to a crawl. Pushing on the back of everyone's mind is the fact that the storm is moving towards them even as they sit there, wasting valuable fuel as they slowly crawl up the Interstate, only to arrive at stations without gasoline and hotels with nowhere to stay.
In a best case situation - at least for these evacuees - the storm either turns now and heads up the Atlantic seaboard or turns after it has passed Florida (Not good news, of course, for Georgia, Alabama, and the Florida Panhandle). In what could be the worst case, it mows right of the center of the state.
Work out the aftermath of that - not in the area of destruction itself but all those who have evacuated. Food and fuel are largely stripped. Their jobs are tied to buildings that may no longer stand and materials that may have been washed out to sea or into the pool across the city. Accounts drain quickly when there is no money coming in - or they drain quickly for the businesses that do not have them coming either.
I am not predicting a collapse (we do not do those sorts of projections around here). But I think it very worthy to note that a collapse - a real, serious, societal collapse - would look an awful lot like one of these scenarios.
A worthy question is how does one prepare for such a circumstance? - yes, I know, move away from there, but that is not always possible for everyone. Imagine you had the deepest preps in the world - and had to leave them all behind? Or what do you take in an uncertain evacuation for an unspecified period of time to an unknown future?
I do not have good answers. I wish I did. Prayer, of course - but there has to be a practical aspect as well.
If ever you wanted to see a "real life" acting of an actual disaster movie, this may be the time. Only foolish will not take note and learn.
