I didn't see any flooding but there was no sign of a crash or a violent incident so I'm guessing the road around the traffic lights flooded and they cordoned off the road until it cleared. Probably re opened the road shortly after I passed.
Nearest houses would be Vine St so I don't think residents were affected.
The ring road was jammed up at the Sky Blue Way exit around the same time, there's normally a slip road there that's a bit susceptible to flooding and that looked to be closed off too. I swerved that and went past Hillfields, flooding would make sense as there was a lot of standing water.
