Matthew was long gone from the Atlantic coast early Monday, but the devastation lingered, most notably in North Carolina, where flooded cities tried to dry out and those downstream kept a close eye on rising rivers. The flooding disaster is forecast to slowly unfold over the next several days as all that rain - more than a foot in places - flows into rivers and downstream, likely causing more inundation in many of the same places devastated by a similar deluge from Hurricane Floyd in 1999. Thousands of people found themselves suddenly trapped in homes and cars during the torrential rains.
