At the end, when all the world leader offcials where at the meeting near the statue of liberty island, couldn't Storm have just wipped up a little rain to have them move the meeting indoors, out of range of Magneto's machine? I mean if there was a chance of hail or lighting they would've had to move all those important people indoors or even delayed the event for a few more days. That kinda would've out the burn on Magneto's plans.
