Jenson Button says it will be "horrible" Brazilian GP for the drivers should the rain continue on Sunday.
The McLaren driver had a difficult time in the rain on Saturday where he qualified down in 15th place with a 1:28.308.
In a session that was dependent on being out on the track at the optimum time, both Button and his team-mate Sergio Perez failed to do just that.
"We struggled because there was so much water and we haven't run when the conditions were this bad," said the Brit.
"We've been trying to save tyres all weekend for qualifying but we made the wrong call."
Looking ahead to Sunday's grand prix at the Interlagos circuit, Button is hoping that the rain lets up and that fans won't be subjected to a Safety Car start if it doesn't.
"If it's wet like this tomorrow it's a horrible race because you can't see anything.
"Hopefully it won't be all under the Safety Car."
