It’s the first G4 watch, but not the first G4 event. In other words, the prior G4 event was not predicted. It can happen that an event is more significant when it arrives than what was predicted, which is what happened here.
A G4 storm was forecast yesterday, but guess what—a G5 was observed: https://www.spaceweather.gov/news/g5-conditions-observed. As with G4 before, not predicted.
It also resulted in Aurora visible in Mexico.
