I've been playing for over 200 hours in my Minecraft world and I only saw the storm happen three times, they are much rarer than on the PC, where I have less than 20 hours of play and I've seen a lot more storms than in the bedrock edition, I believe this is a bug, because storms are very rare indeed, and it seems that they have become even rarer after the last update, I need it to get the heads of the monsters, but I never saw them happen again
