F1 paddock expecting race-day rain at Yeongam

(GMM) The F1 paddock is expecting rain at the new Yeongam venue.

After a dry inaugural race weekend in South Korea so far, forecasts are predicting rain later on Saturday and overnight, with a very high chance of more heavy showers on race-day morning.

And the threat of rain for 1500 local on Sunday – the scheduled race start – is more than 50 per cent, leaving some drivers worried about the effect of a wet track atop the new and already low-grip surface.

"It's going to be tough whatever the weather does," warned McLaren's Jenson Button.
