Heavy rain in Interlagos has delayed the start of the final practice session ahead of qualifying for the Brazilian Grand Prix.
A deluge half an hour before the scheduled 1100 start for FP3 has rendered the track too dangerous for the cars to go out. So far only the safety and medical cars have hit the track to complete installation laps.
The rain is starting to ease now and the race director has confirmed that the session will get underway at 1142, as marshals continue to sweep up the puddles of water.
The teams are predicting further rain later in the session, so running is likely to be kept to a minimum.
Doubt has also been cast over the start time for Saturday’s crucial qualifying hour – in which championship leader Jenson Button will be looking to put himself as close to the front of the grid as possible for his assault on the world title on Sunday.
