Timo Glock expects F1 teams to have to take a gamble on setup tomorrow after Friday practice in Korea was hit by rain.
Drivers will have at the most one hour of dry running in the morning before heading into qualifying, which will lock their setups for the race, meaning that there is little time to recover if the morning setup is incorrect.
"It's not a perfect situation for everyone, but at least we are all in the same boat," said Glock. "It's a gamble for tomorrow to see how the car is in dry conditions.
"Setup wise, you can't do much for dry conditions [in the wet] but in general if the car is OK to drive in wet conditions it should be OK in the dry as well."
The Marussia Virgin driver, who ended the day 21st fastest, is downbeat about the chances of the wet weather continuing on Saturday and Sunday. Wet conditions would likely suit Glock, who ran as high as eighth in last year's race in wet conditions before being crashed into by Sebastien Buemi.
"It was pretty good last year and it opens up some possibilities," said Glock. "But it's pretty clear that it will be dry tomorrow and Sunday so there are no big hopes for us in that direction.
"It felt like there was quite a lot of grip compared to other tracks in wet conditions, but it is challenging. The trouble is that the white lines and the curbs are quite slippery."
