Quoted: Hurricane Harvey made landfall in Texas on Aug. 26, 2017, and lingered in the region for nearly a week. As much as 60 inches of rain fell in the storm, setting a U.S. rainfall record. More than 20 inches of rain fell across about 29,000 square miles. No storm rivals Harvey, said Shane Hubbard, a researcher at the University of Wisconsin who made and mapped that calculation.
