Well I imagine it'll be something involving air/atmosphere manipulation? Since sonic waves are carried through the air, Storm has been shown to instantly draw all the air out of a localized area/create a vacuum...
So I guess it really comes down to a quick draw? Either SB gets a scream off, or Storm flash freezes her, messes with air pressure to implode her from the inside, or some other atmospheric manipulation nonsense that the X-writers have been having her do lately... really nonsensical stuff ever since they declared her an Omega-level mutant, which she never was in the 2000's...
