John Nielsen-Gammon, who is a Regents Professor of Atmospheric Sciences at Texas A&M and also serves as Texas State Climatologist, says Harvey set new standards for historic rainfall and flooding.
"Harvey is head and shoulders above all previous multi-day storms ever recorded in the continental United States," says Nielsen-Gammon.Nielsen-Gammon said that the most amazing record is for the five-day total over an area of 10,000 square miles.
"I examined 18 different combinations of storm lengths and area sizes, from two days long to five days long, and standard areas from 1,000 square miles to 50,000 square miles. According to the preliminary data, Harvey was the worst in all but one."
"For Harvey to average 34.72 inches over five days across that large an area is ridiculous," Nielsen-Gammon says. "The previous all-time United States record, set in Texas back in 1899, was estimated at 21.39 inches. Harvey exceeded that record by 62 percent."
