Houston, you have a problem.
From The New York Times, "Houston before and after Harvey."
Harvey, the storm that has hit the Houston area hasn't been a typical hurricane/tropical storm. It's really quite different. Unlike most hurricanes, it hasn't passed through and moved on. In fact the storm is stuck above the Houston and continuing to inundate the area with heavy rains.
Scientific American offers an explanation of the forces in play that have made Harvey one of a kind. The important question is whether Harvey is just a freak storm or the face of a new hurricane reality for the southern U.S.
