Ororo can shut down her nervous system with a passing thought by controlling the electrical impulses in her brain (same as she did to Sinister). She can batter her senseless (or even to death) with elemental barrages (we have seen Storm lift skyscrapers on her winds, knock back tsunami waves that weighed a million tons=1 billion pounds coming at her at hundreds and hundreds of miles per hour, we have seen Storm redirect the full power of a mutant strong enough to split the planet like a ripe melon, we have seen her blow up a Herald of Galactus, she just one-shotted Adversary recently in Black Panther nearly disintegrating him with her attack, she has destroyed near-Godzilla-sized monsters made up of vibranium with the force of her elemental fury, she can freeze the veins and heart in Nova's body, or control the air in her lungs, she can manipulate the pressure inside of Nova).
Here, we see Nova easily best Jean telepathically:

Jean does manage to separate her from Logan with a creative use of her TK powers, but doesn't even slow Nova down.

Well, now she fears Jean and not Ororo, huh? When Storm has been able to defeat psis stronger than Nova...
Looks like a lot of canon is about to be ignored for Jean in this story arc.
