Storm was a caffeinated lemon-lime flavored soft drink. It was test marketed by PepsiCo in some areas of the U.S. in 1998 as part of Pepsi's attempt to become more competitive in the U.S. clear lemon-lime soda market, one which was dominated by the The Coca-Cola Company's Sprite. Storm differed from Sprite in that its flavor was uniquely subtle and had a very slight bitterness to it.
Pepsi already had an existing offering, lemon-lime Slice, although it, like Sprite, was caffeine-free.
Pepsi dropped Storm while it was still in the test market stage. Lemon-lime Slice was dropped in favor of a new formula, marketed as Sierra Mist in 2000.
