Between Aug. 10 and 17, nearly 30 inches of rain fell in parts of Louisiana. Some of the worst flooding occurred around Lafayette and Baton Rouge. The $10 billion disaster claimed at least 13 lives and destroyed more than 50,000 homes, according to National Oceanic and Atmospheric Administration.

The rain resulted from a slow-moving area of tropical low pressure that drew record-setting amounts of moisture from the Gulf of Mexico over Louisiana. It produced three times as much rain as Hurricane Katrina, and was the worst flood disaster in the U.S. since Superstorm Sandy.

In June, 23 people were killed by flash flooding in West Virginia after 10 inches of rain fell over the course of 12 hours. Rivers crested at all-time highs as water surged down the mountainous drainage basins. Greenbrier County was devastated by the flooding, and County Sheriff Jan Cahill described the scene as “complete chaos.”

To end the year of flooding, Hurricane Matthew swept up the Southeast Coast and poured 18 inches of rain on parts of North and South Carolina in early October. Rivers crested at levels not seen since Hurricane Floyd in 1999, and nearly 30 people died as a result of the multi-day floods.

In Robeson County, N.C., children did not return to school until Oct. 31 — more than 20 days after Hurricane Matthew struck the region.
