I am more like a scientific minded, than a mystic so here is my view.

So first of all, we have to decide, what is the storm.

-1. It's an after effect of using the rewind.

-2. It's an after effect of Chloe is alive.

If it's the effect of Chloe, than only the let her die is a good ending. If you choose to sacrifice arcadia bay, the cause, that Chloe is still alive, will not be dissapering, so there is no proof, that even more cataclysmic things would not be coming, to fix the mistake, aka kill Chloe.

if it's just the effect of usingthe rewind:

You can treat the whole game in different ways.

-1, all the happenings in the game are a paradoxon. You start manipulating the time line, but at the end, you undo your first decission, and nothing is changed, so the paradox is healed itself, like the killing your younger self paradox.

-2. You not creating a paradoxon in the end, rather you alter again the timeline where you didn't started to use your force in the toilet.

Both of this types in my view denying the ending.

if #1 all the changes in the paradox have no effect for the ending timeline, so you could just simply hit the firealarm, and bust jefferson with a message.

if #2, that also means, that either the tornado ocured ony in the alternative timelines where you constantly usedyour power, so again, hit the firealarm without using rewind in the past, and send a message to david.

The 'chain reaction' or 'chaos effect' is not just because she changed the iutcomes, but CONSTANTLY changing it. So Leaving chloe alive would have no much effect on the timeline's in the end. Because either, the effect would occour in the paradox, or in the alternative timeline with the tornado, where you constantly used your power.
