According to the National Hurricane Center, Tropical Storm Harvey is rapidly strengthening and is now forecast to become a “major hurricane” when it hits the middle Texas coast.”Major hurricane” means Category 3 (winds of at least 111 mph or higher). Even more deadly than the winds are the potential of catastrophic flooding as the tropical storm bears down on the Gulf Coast. It could reach hurricane status as meteorologists predict potential historic rainfall over the next several days in parts of Texas and Louisiana.
