Does the storm's fury ever end?

I’m levelling an alt and am only level 24. I’m on the bronze dragonflight bit and am in the Primalist Future. When the event is on (4/4 tries so far) I cannot do the quests because the mobs scale to 70 and the non elite mobs don’t drop anything anyway.

The internet says it’s five hours long but I can’t seem to catch 5 mins when it’s not on.

edit - I’ve made note of the wowhead timer but they only work half of the time, so I’ll check then. This is so infuriating. My daughter only wants to see Azmerloth (she thinks it’s hilarious).
