Motor Sport:A thunderstorm over Sao Paulo today delayed the start of final practice ahead of tomorrow's Brazilian Grand Prix.
The storm broke 30 minutes prior to the hour-long session at Interlagos, and although it eventually eased, it was still raining come the official start time of the practice period.
Given the low cloud made visibility exceptionally poor, the weather grounded the medical helicopter, resulting in the FIA announcing the delay.
