Prophecies generally aren't known until after the time has passed. If the "world" is referring to Gaea. Percy and/or Jason could be the storm, but it could mean something else. Leo seems to have the biggest problem with Gaea as she has pretty much destroyed his family and past, so if anyone is fire then it is Leo, but like I said, we won't know until it happens.
