Back in August of 2016 Louisiana flooded. This isn't the first time that Louisiana has flooded. Researchers may have discovered the reason behind Louisiana's constant flooding.
A combination of tropical moisture and low pressure fueled the immense rainfall in Louisiana and southwest Mississippi, meteorologists said. When so much moisture is in the atmosphere, storms can produce rainfall of several inches in a single hour, resulting in astronomical totals over time. With rainfall totals in the double digits NASA's Global Precipitation Measurement mission estimated more than 20 inches (508 millimeters) of rainfall in large areas of southeastern Louisiana and southern Mississippi rivers were rapidly rising, causing serious flooding. At least six rivers in Louisiana have hit record levels. The most extreme flooding has occurred along the Amite River, which exceeded its previous height record in Magnolia, Louisiana, by more than 6 feet (1.8 meters).
The NWS also noted that the moisture content in the atmosphere was close to an all time record for the area, even higher than observations during some tropical cyclones.
