Actually that would be X-Men Unlimited 6, X-Men Unlimited 39 and somewhat in Xtreme X-Men 46(IIRC).
I’m guessing you haven’t read Uncanny X-Men 95, 116 and 156 where Storm summons a large amount of water to forcefully remove her foes. Also Storm control clouds which are made of small droplets of water or bits of ice that are spread out from each other, with this ability she has create humanoid shapes (UXM 472)
Storm and Iceman both control water and temperature mentally. Storm ability to create ice was strong enough to hold Colossus (at the time, a Class 80 tons character, UXMA 6).
Actually it the other way around, Storm can do just about everything Bobby can do with water and temperature, along controlling the weather and summon solar flares.
While making pretty ice sculptures and transform into water is a nice trick, what can Bobby do that Ororo can't do on an even greater scale?
Let’s see, Storm can stimulate the creation of any form of precipitation (rain, snow, sleet, hail, fog) and even sense the composition of rainwater (Storm 2). Her manipulation of water has ranged from controlling ocean currents (XMU 39) to using raindrops as a lens to filtering out certain forms of solar energy (XMHY 6). She can even manipulate the surface tension of water enough that she can actually surf on it (XXM 46). Storm also has shown the ability to sense the movement of object while in the darkness of ocean water (XMU 39).
You might want to read a little more on Storm if you think she doesn't have a chance of surviving in this enviroment.
