April 2016 North American storm complex

The April 2016 North American storm complex was a major storm system that resulted from an upper-level low in the United States stalling and producing record-breaking rain in and around Houston, Texas, resulting in severe flooding, as well as a major snowstorm in the Rocky Mountains. There were more than 17 inches of rain in one day in parts of the city, and up to 4 inches of rain per hour that morning at George Bush Intercontinental Airport.
