Storm was a lemon-lime flavored soda with caffeine that only lasted two years before being replaced with Sierra Mist, and didn't get out of the test market stage. Pepsi included it in their marketing of Star Wars: Episode I – The Phantom Menace, and offered cans with characters in both Storm and Light Storm varieties. Test markets included Denver, Indianapolis, Omaha, San Francisco, Sacramento, Grass Valley Las Vegas, Milwaukee, and Philadelphia. But in the end, lemon-lime Slice and Storm were dropped in favor of a new formula, marketed as Sierra Mist.
