I am currently trying to catch Tornadus in Black 2.
After forgetting about it until after I defeated the Champion, I returned to Route 7 to trigger the Tornadus event.
Strangely, there was no storm, and there was no event starting grandma outside.
Is there a specific event to trigger the hunt?

Tornadus and Thundurus only show up in Pokemon Black/White respectively, and not in their sequels.
To obtain those Pokemons, you need to either use the Dream Radar app on the 3DS, or trade them from Pokemon Black/White.
