The storm was fueled by a weather phenomenon behind some of California's wettest and most destructive storms. Atmospheric rivers are long plumes of moisture over the Pacific Ocean that tend to move through the atmosphere in streams between 250 and 375 miles wide.

The rivers in the sky move a staggering amount of water. One atmospheric river can move an average of 10.5 trillion gallons of water per day.

The strongest atmospheric rivers can move anywhere between seven and 25 times as much water as the flow of the Mississippi River, which is the second longest river in North America and has a watershed that reaches 32 states, according to the national park service.
