All of you are thinking about this wrong. We're told it's been
one week since the battle.
Meryl says they were suppose to get a week of stormy weather, but Izuku's punch made all of that go away and has instead been clear skies.
This is still an insane feat, in fact it's better than I thought. They're still feeling strong winds from Izuku's punch even after one week.
Have a good feeling this is going to be a significant upgrade. Can't say when I'll have anything yet, but I am working on this.
Izuku's punch producing strong winds even one week later is insane.
