No one in America has ever experienced the wrath and fury of a category 6 hurricane, which now genuinely seems possible and realistic. We’ve been lucky. Unofficial category 6 hurricanes have appeared in other parts of the world, and we’re seeing much stronger storms on a regular basis. It’s only a matter of time before one hits the US.
When it does, it will come as quite a shock. The devastation we saw in 2017 in Houston, several Caribbean islands, and Puerto Rico may actually pale in comparison.
