Writing off a tropical cyclone simply because it has moved inland is one of the big mistakes people do. Sure, most of the time things go as expected. But sometimes, and not all that infrequently, really, inland TCs at the very least unleash all of their rainfall potential over a very concentrated area by a process which results in core rains. At other times, although pretty rare, they can even intensify over land, as Fay did. In either case, the results can be exceptional, and catch many people who let their guard down, totally off guard.
