The storm first developed on August 17, 2017, from a tropical wave to the east of the Lesser Antilles. It faded into an open tropical wave on August 19. But on August 24, Harvey redeveloped into a tropical storm, and then strengthened into a hurricane. On August 25, Harvey rapidly strengthened into a Category 4 hurricane with maximum sustained winds of at least 130 mph, and it made landfall in Texas as a low-end Category 4 hurricane. On August 26, Harvey stalled and rapidly weakened into a tropical storm in just a few hours after making landfall, resulting of dumping heavy rainfall and caused major and catastrophic flooding in parts of southeastern Texas especially the Houston metropolitan area.
