New For 2018: Typhoon Twister! SFSL New 2018 | Six Flags St Louis Hybrid Zero-Gravity Slide Coming to Hurricane Harbor Water Park Six Flags St. Louis, the Coaster Capital of Missouri, announces Typhoon Twister, a massive new water attraction, headed to Hurricane Harbor in 2018. This hybrid, zero-gravity slide complex packs two extreme slide thrills into one amazing attraction. “Six Flags St. Louis takes great pride in offering our guests new, groundbreaking rides and attractions every year. For 2018, Six Flags leads the way in innovation again as Typhoon Twister is unlike any other water attraction, giving riders two completely different thrill experiences in one very intense slide,” said Park President Pete Carmichael. “This one-of-a-kind experience is another big reason why our guests will want to enjoy both the water park and the theme park during their visits next year. Typhoon Twister features four-person rafts that careen wildly into a 125-foot long whirlpool bowl that spins riders around 360 degrees before the bottom drops out, sending guests plummeting down an enclosed five-story drop. Storm chasers will then be propelled up a 45-ft. zero-gravity wave wall to experience moments of weightlessness before falling back down and shooting out into the splash pool below. Typhoon Twister highlights include: A hybrid, zero-gravity drop slide; 125-ft long whirlpool bowl with a 54-ft vertical drop; A unique 45-ft. high wave wall that sends riders into weightlessness; Cloverleaf tube seats four people all facing each other; and Pumps 300,000 gallons of water per hour. Typhoon Twister, scheduled to make landfall in May 2018, is the latest addition to the 12-acre water park which is offered free with theme park admission. Riders must be a minimum of 48” tall to brave Typhoon Twister.
