Fans arriving at the Hungaroring on Sunday morning had best bring their umbrellas as rain is forecast.
Sunday morning's GP3 race took place on a wet track while the drivers in the GP2 race, which ended less than four hours before this afternoon's Formula One race, took the chequered flag under a deluge.
It proved to be an interesting strategic battle as race winner Stefano Coletti started 21st on the grid and on slick tyres - even though the track was wet. He took advantage when his rivals later pitted for slicks and was up near the front when everyone had to return to wet tyres just a handful of laps later.
And with more rain forecast for this afternoon's F1 race, it should be exciting to see who handles the conditions and the strategies the best.
McLaren, who are starting second and third on the grid with Lewis Hamilton ahead of Jenson Button, will be relishing the cooler conditions while Ferrari and Mark Webber and those behind them will be hoping that rain can level the playing field.
As for pole sitter Sebastian Vettel, wet or dry, he'll want to stay ahead of the McLarens at the start.
