If the forecasts are accurate, it will absolutely rain on the recording industry’s parade.

That’s right, Keith Urban, 5 Seconds of Summer, Troye Sivan and Rita Ora won’t be the only ones making a splash at Wednesday’s ARIA Awards. The big wet is coming, just when we don’t want it.

Meteorologists are urging Sydneysiders to brace themselves for a hammering. While the gods of rock and pop stroll the red carpet at The Star, the heavens should open and dump anywhere from 60mm to as much as 120mm on the city in just a few hours, as a concentrated low pressure area hones in.

That’s not some light drizzle. According to the Bureau of Meteorology, November’s average rainfall in Sydney is 66mm, so the host city of the 2018 ARIA Awards is facing almost two months of rain in just a few hours.

“Current forecasts indicate intense rain could occur in major population centres from Wednesday morning. Damaging winds and hazardous surf conditions are also anticipated,” a BOM alert reads.

That means delays for interstate guests, soggy suits and mushy hairdos. The upside, well, it shouldn’t too hot.

Forecaster Jordan Notara told the ABC some parts of Sydney may even flood. Oh, and wind.
